Abstract
Description
前記保護層が、活性光線硬化樹脂およびフィラーを含み、
前記活性光線硬化樹脂が、重合成分として、多官能ウレタン(メタ)アクリレートを含み、
前記フィラーの体積平均粒子径が、40nm以下である、転写箔が提供される。
本明細書において、配合を示す「部」、「%」、「比」などは特に断らない限り質量基準である。また、「PET」は「ポリエチレンテレフタレート」の略語、同意語、機能的表現、通称、または業界用語である。また、活性光線硬化性樹脂とは活性光線を照射する前の前駆体または組成物を意味し、活性光線を照射して活性光線硬化性樹脂を硬化させたものを活性光線硬化樹脂というものとする。
本発明の実施の形態を、図面を参照しながら詳細に説明する。図1及び図2は、本発明の一実施形態による転写箔の断面模式図を示したものである。本発明による転写箔は、基材10と、基材10上に剥離可能に設けられた保護層20を備えている(図1参照)。このような転写箔1を用いて被転写体(図示せず)へ転写層40を転写すると、保護層20が転写層40として、被転写体へ転写される。また、保護層20上には、接着層30が設けられていてもよい(図1参照)。また、基材10から保護層20が剥離して転写層40が被転写体へ転写され易いように、基材10と保護層20との間に離型層50が設けられていてもよい(図2参照)。また、保護層20と接着層30との間にプライマー層60が設けられていてもよい(図3参照)。さらに、転写箔には、受容層70が、保護層20またはプライマー層60と接着層30との間に設けられていてもよい(図4および図5参照)。さらに、基材10と離型層50との間にアンカー層が設けられていてもよい(図示しない)。なお、後述するように、所望により設けられる接着層は、その構成を調整することにより受容層としての役割を果たすこともできる。
以下、本発明による転写箔を構成する各層について、説明する。
基材としては、転写箔から転写層を被転写体へ転写する際の熱エネルギー(例えば、サーマルヘッドの熱)に耐え得る耐熱性を有し、転写層を支持できる機械的強度や耐溶剤性を有しているものであれば、特に制限なく使用することができる。例えば、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタレート、ポリエチレンテレフタレート-イソフタレート共重合体、テレフタル酸-シクロヘキサンジメタノール- エチレングリコール共重合体、ポリエチレンテレフタレート/ポリエチレンナフタレートの共押し出しフィルムなどのポリエステル系樹脂、ナイロン6、ナイロン66などのポリアミド系樹脂、ポリエチレン、ポリプロピレン、ポリメチルペンテンなどのポリオレフィン系樹脂、ポリ塩化ビニルなどのビニル系樹脂、ポリアクリレート、ポリメタアクリレート、ポリメチルメタアクリレートなどのアクリル系樹脂、ポリイミド、ポリエーテルイミドなどのイミド系樹脂、ポリアリレート、ポリスルホン、ポリエーテルスルホン、ポリフェニレンエーテル、ポリフェニレンスルフィド、ポリアラミド、ポリエーテルケトン、ポリエーテルニトリル、ポリエーテルエーテルケトン、ポリカーボネート、ポリエーテルサルファイトなどのエンジニアリング樹脂、ポリスチレン、高衝撃性ポリスチレン、AS樹脂(アクリロニトリル-スチレン共重合体)、ABS樹脂(アクリロニトリル-ブタジエン-スチレン共重合体)などのスチレン系樹脂、セロファン、セルロースアセテート、ニトロセルロースなどのセルロース系フィルム、などが挙げられる。
次に、転写層を構成する保護層について説明する。
保護層は、活性光線硬化樹脂およびフィラーを含み、被転写体表面の保護を担うものである。
次に、本発明による転写箔が所望により備える接着層について説明する。
接着層は、転写箔の表面に位置するように設けられ、転写層と、被転写体との接着性を向上させるものである。さらに、この接着層は、熱転写によって、色材層を有する熱転写シートから熱転写法によって画像が形成される、受容層としての機能を果たすものであっても良い。そして、画像が形成された転写箔の転写層は、被転写体に転写され、その結果、印画物が形成される。
次に、本発明による転写箔が所望により備える離型層について説明する。
離型層は、基材上に設けられ、離型層上に設けられる転写層を、転写箔から剥離して被転写体へ転写させるための層である。なお、転写層を転写箔から剥離する際、離型層は基材側に留まる。
次に、本発明による転写箔が所望により備えるプライマー層について説明する。
プライマー層は、保護層上に設けられる。また、プライマー層は、熱可塑性樹脂と、イソシアネート化合物とを含むことが好ましい。熱可塑性樹脂としては、ポリエステル樹脂、ポリウレタン樹脂、アクリル樹脂、ポリカーボネート樹脂、ポリビニルアルコール樹脂、塩化ビニル-酢酸ビニル共重合体およびポリビニルブチラール樹脂などが挙げられる。これらの中でも、ポリエステル樹脂および塩化ビニル-酢酸ビニル共重合体が好ましく、ポリエステル樹脂および塩化ビニル-酢酸ビニル共重合体を併用することがより好ましい。ポリエステル樹脂および塩化ビニル-酢酸ビニル共重合体を併用する場合、これらの配合比(ポリエステル樹脂/塩化ビニル-酢酸ビニル共重合体)は、質量基準で、1/40以上、30以下であることが好ましく、1/30以上、20以下であることがより好ましく、1/25以上、15以下であることがさらに好ましく、1/2以上、6以下であることが最も好ましい。また、プライマー層中における熱可塑性樹脂の含有量は、プライマー層の固形分総量に対し、50質量%以上、90質量%以下であることが好ましく、60質量%以上、90質量%以下であることがより好ましい。熱可塑性樹脂の含有量が上記数値範囲内であることにより被転写体または接着層との接着性をより高めることができる。
次に、本発明による転写箔が所望により備える受容層について説明する。
上述の通り、本発明の転写箔が所望により備える接着層は、その構成を調整することにより、受容層としての役割を果たすが、転写箔は、受容層を備えていてもよい。この場合、受容層は、保護層またはプライマー層上に設けられ、この受容層上には、熱転写によって、色材層を有する熱転写シートから熱転写法によって画像が形成される。そして、画像が形成された転写箔の転写層は、被転写体に転写され、その結果、印画物が形成される。また、所望により、この受容層上に接着層が設けられる。
本発明による転写箔を用いて、被転写体上に転写層を転写する方法としては、公知の転写法でよく、例えば、熱刻印によるホットスタンプ(箔押)、熱ロールによる全面またはストライプ転写、サーマルヘッド(感熱印画ヘッド)によるサーマルプリンタ(熱転写プリンタともいう)などの公知の方法が適用できる。好ましくは、ホットスタンプである。
厚さ12μmのポリエチレンテレフタレート(PET)フィルムの一方面にメラミン系樹脂の離型層が塗布されたフィルムを基材として用い、その離型層上に、下記の組成からなる保護層塗工液をグラビアコーティングにより、乾燥後の厚みが6μmになるように塗布し乾燥させた後に、UV露光器(Fusion UV、F600V、LH10ランプ、Hバルブ、反射鏡はコールドタイプ)を用いて紫外線を照射し、保護層を形成した。
