Title
(EN) SELF-ADHESIVE FOAM SHEET
(FR) FEUILLE DE MOUSSE AUTO-ADHÉSIVE
(JA) 自己吸着性発泡シート
Abstract
(EN)
Provided is a self-adhesive foam sheet including: 100 parts by mass of a (meth) acrylate ester copolymer resin having an N-methylol group and a glass transition temperature of no more than -10°C; and 1-20 parts by mass of a carbodiimide-based crosslinking agent. The self-adhesive foam agent comprises a foamed body formed into a sheet shape then cross-link reacted with the (meth) acrylate ester copolymer resin, said foamed body being a resin composition for self-adhesive foam sheets that has been foamed. Also provided is a self-adhesive foam laminated sheet having: an adhesive layer comprising the self-adhesive foam sheet; and a supporting layer comprising a base material. The self-adhesive foam sheet and the self-adhesive foam laminated sheet have an extremely low formaldehyde generation, an appropriate amount of self-adhesion, and excellent smoothness.

L'invention concerne une feuille de mousse auto-adhésive comprenant : 100 parties en poids d'une résine de type copolymère d'ester de (méth)acrylate ayant un groupe N-méthylol et une température de transition vitreuse d'au plus -10°C ; et de 1 à 20 parties en poids d'un agent de réticulation à base de carbodiimide. L'agent de mousse auto-adhésive comprend un corps expansé façonné sous la forme d'une feuille qui est ensuite soumis à une réaction de réticulation avec la résine de type copolymère d'ester de (méth)acrylate, ledit corps expansé étant une composition de résine pour feuilles en mousse auto-adhésives qui a été expansé. L'invention concerne également une feuille stratifiée en mousse auto-adhésive comprenant : une couche adhésive comprenant la feuille en mousse auto-adhésive ; et une couche de support comprenant un matériau de base. La feuille en mousse auto-adhésive et la feuille stratifiée en mousse auto-adhésive génèrent des émissions de formaldéhyde extrêmement faibles, présentent une quantité appropriée d'auto-adhérence, et une excellente douceur au toucher.
