接合性に漬れたウレタン組成物の開示がある。[Prior Art] Conventionally, automobile instrument panels and the like have been constructed such that the surface of a hard urethane foam body is coated with a soft vinyl chloride skin. To manufacture this instrument panel, a vinyl chloride sheet is placed in a mold, a urethane resin is injected and foamed, and the molded body and the skin are integrally bonded. For example, JP-A-62-146909 discloses a urethane composition that is highly bondable to vinyl chloride skin.

And the soft epidermis is formulated with a large amount of plasticizer. However, when a heat aging test is conducted on the integrally foamed molded article formed as described above, the vinyl chloride skin may undergo thermal deterioration, resulting in a decrease in performance such as tensile elongation. Additionally, phthalate ester plasticizers are known to migrate easily, and
There may be a transition from the porcelain vinyl skin to the foamed urethane molded product. This transition occurs more easily at higher temperatures. When plasticizers in the epidermis decrease in this way, the epidermis becomes hard and
A problem arises in that flexibility becomes insufficient.

Since then, I have undertaken intensive research. As a result, we have completed the present invention by discovering that an excellent synergistic effect can be achieved by using two specific hrt additives in combination.

The present inventors have discovered that by using a phosphoric acid ester as an additive for a foamed urethane molded article, the effect of the trimellitic acid ester described below can be further enhanced. In other words, when a heat aging test is conducted on an integrally foamed molded product, when trimellitic acid ester is added to the chloride building surface, those with added phosphate ester have significantly longer flexibility than those without. They found that it was possible to maintain the .
