Agents such as carbonates, sulfides, dietrosopentamethylenetetramine (DPT), etc. that react with the acidic catalyst in the overcoating paint to generate decomposed gas are mixed into the ink, and the ink is used to coat the substrate. After printing the pattern, paint is applied on top of it, and the decomposed gas generated during this process is captured in the paint film.Then, the paint layer on this foamed area is ground to expose the ink surface and the printed pattern is created. The method for manufacturing decorative laminates is to form recesses that are completely in sync with the
It is disclosed in Japanese Patent Publication No. 51-30099 and Japanese Patent Publication No. 51-49246.

Decorative boards manufactured by the above method may have printing ink exposed at the bottom of the recesses that match the pattern formed by grinding the surface, or small scratches caused by grinding on smooth areas of the coating. Since this impairs the smoothness of the paint film, an additional top coat was applied to the entire surface in order to protect the ink surface and improve its appearance.
そのため、化粧シートの製造工程は、印刷、塗

要とし、化粧シートの価格としても通常よりは高
価にならざるを得なかつた。 Therefore, the manufacturing process for decorative sheets basically requires four steps: printing, coating drying, grinding, and coating drying, and the price of decorative sheets has to be higher than usual.

This invention involves printing a pattern on the surface of a sheet using an ink containing a chemical that reacts with the acidic catalyst of the acidic curable resin to generate decomposed gas, and then
A paint made by adding and mixing an amino alkyd resin and an acidic catalyst to an unsaturated polyester resin is applied, and the paint is dried and cured at a temperature higher than that which rapidly accelerates the curing reaction of the unsaturated polyester resin. A paint in which an unsaturated polyester resin and an aminoalkyd resin are added and mixed on the top surface of the printing ink by raising the paint applied on the printed pattern to form convex portions, and then grinding the convex portions on the same pattern. This is a method for producing a decorative material that omits the top coating process after grinding by applying and drying at a high temperature.

ことと、インク中の分解ガスを発生する薬剤の分
解及びアミノアルキツド樹脂の硬化をできる限り
少量の酸性触媒で行わせるためである。 In this invention, a paint mixture of an unsaturated polyester resin and an aminoalkyd resin is used, an acidic catalyst is added, and the paint is dried at a high temperature that rapidly accelerates the reaction of the unsaturated polyester resin. This is because the ink is cured by temperature without using a catalyst or accelerator, and the decomposition of the agent that generates decomposed gas in the ink and the curing of the aminoalkyd resin are carried out using as little acidic catalyst as possible.
なお、不飽和ポリエステル樹脂は硬化するとア
ミノアルキツド樹脂に比べて硬いので、発泡部分
の研削作業は非常に容易となり砥粒のついていな
い研磨具で軽く研削するだけで発泡部分を取り除
くことができ、塗膜の他の平滑部分まで研削しす
ぎて傷をつけたりすることがほとんどない。 Furthermore, since unsaturated polyester resin is harder than aminoalkyd resin when cured, it is very easy to grind the foamed parts, and the foamed parts can be removed just by lightly grinding with a non-abrasive polishing tool, and the coating film can be removed. There is almost no chance of scratching other smooth parts of the machine by grinding too much.
また、非発泡部ではポリエステル樹脂とアミノ
アルキツド樹脂の一部が温度により架橋反応して
非常に強靭な塗膜を作ることによる。 In addition, in the non-foamed area, a portion of the polyester resin and aminoalkyd resin undergo a crosslinking reaction due to temperature, creating a very tough coating film.
この発明において用いるシート状物は、重さが
20〜80ｇ／m2程度の紙や合成紙、あるいは厚さが
0.05〜0.5mm程度の合成樹脂フイルム等であり、
特に価格が安価であるだけでなく、表面が平滑で
印刷適性に優れている点から重さが23〜30ｇ／m2
の薄葉紙が好適である。 The sheet-like material used in this invention has a weight of
Paper, synthetic paper, or thickness of about 20 to 80 g/m2
It is a synthetic resin film of about 0.05 to 0.5 mm,
In particular, it is not only inexpensive, but also has a smooth surface and excellent printability, with a weight of 23 to 30 g/m 2
Tissue paper is suitable.

薬剤であるDPT、硫化カルシウムや硫化鉄等の
硫化物、炭酸カルシウムや炭酸バリウムさらには
重炭酸アルカリ等の炭酸塩等を添加する。 Next, two or three layers of ink are printed on the top surface of the sheet using a normal gravure printing device to form a pattern. Use DPT, which is a chemical that reacts with acidic catalysts to generate decomposed gases such as nitrogen gas, sulfide gas, and carbon dioxide, as well as sulfides such as calcium sulfide and iron sulfide, and calcium carbonate, to ink only in areas where you want to express depressions. Carbonates such as barium carbonate and alkali bicarbonate are added.

スを利用してインクの上面に塗布された塗料の塗
膜を隆起させる。 That is, calcium sulfide, iron sulfide, calcium carbonate, barium carbonate, alkali bicarbonate, etc., are inorganic acids, organic acids, acidic catalysts such as amino alkyd resins and acidic curing phenolic resins, acidic substances such as butyl phosphate, ammonium chloride, etc. It is known that ink reacts with substances that generate acids to generate nitrogen gas, sulfide gas, carbon dioxide gas, etc., and this generated gas is used to raise the paint film applied to the top surface of the ink.
インク中に添加する上記薬剤の配合量として
は、インク100重量部に対して30〜50重量部の範
囲である。 The amount of the above-mentioned drug added to the ink is in the range of 30 to 50 parts by weight per 100 parts by weight of the ink.
次に、上記の印刷模様全面に不飽和ポリエステ

とができる。 Next, a resin paint made by adding and mixing an aminoalkyd resin and an acidic catalyst to an unsaturated polyester resin is applied to the entire surface of the above printed pattern. In addition, by adding a small amount of a mold release agent such as a silicone resin to the paint, the peeling resistance of the paint film due to cellophane adhesive tape can be improved, and by adding an extender pigment, the gloss of the paint film can be adjusted.
この発明において使用する不飽和ポリエステル
樹脂は、分子量が2000〜5000、酸価が10〜20、固
形分が70％程度の常用の塗料用樹脂液でる。 The unsaturated polyester resin used in this invention is a commonly used paint resin liquid having a molecular weight of 2,000 to 5,000, an acid value of 10 to 20, and a solid content of about 70%.
そして、上記の樹脂液に混合されるアミノアル

捉しなければならないので、通常よりもはるかに
多い13〜20ｇ／m2程度が必要で、この塗布量をで
きるだけ少なくして、しかも紙の裏側への浸透抜
けを少なくして塗布しようとするためである。 The amino alkyd resin paint to be mixed with the above resin liquid is a high solids resin paint with a mixing ratio of amino resin and alkyd resin of 2:8 to 6:4 and a resin solid content of about 65 to 80%. . The reason for using a paint with a high resin solid content is that in the case of decorative paper with a smooth surface, the amount of paint applied was conventionally about 5 to 8 g/m2, but in the present invention, the decomposed gas must be captured by the coating film. Therefore, a coating amount of about 13 to 20 g/m 2 is required, which is much higher than usual, and the aim is to reduce this coating amount as much as possible, and to reduce penetration to the back side of the paper.
更に、上記の塗料に添加される酸性触媒は、塩
酸、硫酸等の無機酸やパラトルエンスルホン酸、
燐酸ブチル、蟻酸等の有機酸、塩化アンモニウム
等の酸を生じる物質である。 Furthermore, the acidic catalysts added to the above paints include inorganic acids such as hydrochloric acid and sulfuric acid, p-toluenesulfonic acid,
It is a substance that generates organic acids such as butyl phosphate and formic acid, and acids such as ammonium chloride.
それぞれの添加量としては、上記の不飽和ポリ
エステル樹脂50〜60重量部に対してはアミノアル
キツド樹脂40〜50重量部と酸性触媒が５〜８重量
部程度である。 The respective amounts of the aminoalkyd resin and the acidic catalyst are about 5 to 8 parts by weight per 50 to 60 parts by weight of the above-mentioned unsaturated polyester resin.
なお、酸性触媒は多量に添加すると塗膜中に残
存して塗膜の劣化を促進するため、添加量はでき
る限り少量に抑え、加熱による反応促進を図るほ
うが好ましい。 Note that if the acidic catalyst is added in a large amount, it will remain in the coating film and promote deterioration of the coating film, so it is preferable to keep the amount added as small as possible and to promote the reaction by heating.
そして、塗布された塗料は不飽和ポリエステル
樹脂の反応が急激に促進される温度、通常は150
℃以上の高温で乾燥硬化を図り、分解ガスで印刷
模様上部の塗料を隆起させて凸部を形成する。 The applied paint is heated at a temperature at which the reaction of the unsaturated polyester resin is rapidly accelerated, usually at 150°C.
The paint is dried and cured at a high temperature of ℃ or higher, and the decomposed gas causes the paint on top of the printed pattern to bulge to form convex parts.
塗膜が発泡隆起した凸部の研削は、研磨ロール
に砥粒のついていない高速回転する布バフを用い
てシートの表面を軽く磨くことによつて行うこと
によつて凸部を形成して脆くなつた塗膜は容易に
除去されて凹部を形成する。 Grinding of the convex parts where the coating film is foamed and raised is done by lightly polishing the surface of the sheet using a high-speed rotating cloth buff with no abrasive grains attached to the polishing roll, thereby forming convex parts and reducing brittleness. The worn-out paint film is easily removed to form recesses.
なお、この際、凹部のインク面はアミノアルキ
ツド樹脂塗膜で覆われているので、化粧シートの
品質としては全く問題ない。 At this time, since the ink surface of the recessed portion is covered with the aminoalkyd resin coating, there is no problem with the quality of the decorative sheet.

The method for producing a decorative material of the present invention uses a paint mixture of an unsaturated polyester resin and an aminoalkyd resin, adds an acidic catalyst, and dries at a high temperature that rapidly accelerates the reaction of the unsaturated polyester resin. Unsaturated polyester resins are cured mainly through temperature reactions, and aminoalkyd resins are cured even with a small amount of acidic catalyst.At the same time, the chemicals in the ink rapidly decompose and form bubbles in the coating film, making it easy to create convexities that match the pattern. can be formed into

どない。 In addition, the unsaturated polyester resin in the coating film is harder than the amino alkyd resin when cured, so the resin in the foamed parts becomes very brittle, making it very easy to grind the convex parts, and even other smooth parts of the coating film. There is almost no need to grind excessively and cause scratches.

としては全く問題がない。 On the other hand, the coating film in the non-foamed area is tough due to a crosslinking reaction between a portion of the polyester resin and the amino alkyd resin, but has a moderate degree of flexibility.
Furthermore, the paint film on the foamed parts can be easily removed, so
The ink surface of the recessed portions was covered with an aminoalkyd resin coating that was not completely removed, and there was no problem with the quality of the decorative sheet.

優れた化粧シートを得ることができる。 Because it dries at high temperatures, the amount of acidic catalyst added to cure the amino alkyd resin can be kept to a minimum, reducing deterioration of the coating film, etc.
Compared to the conventional manufacturing process for decorative sheets, a decorative sheet with excellent performance and appearance can be obtained even though the overcoating step can be omitted.
