Title:
PHOTOSENSITIVE RESIN COMPOSITIONS, CURED ARTICLES OF THE COMPOSITIONS, AND FILMS CONTAINING THE COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO/2006/120887
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a photosensitive resin composition suitable for hard coats which permits thick coating with low curling and little causes crack, and to provide a resin composition for the protective coating for high-density optical discs which is excellent in transparency and the resistance to water absorption and which exhibits high endurance with little warpage, and cured articles of the composition. [MEANS FOR SOLVING PROBLEMS] A photosensitive resin obtained by reacting an isocyanate compound (A) prepared by reacting a diisocyanate compound (a) with an alcohol compound (b) having at least two hydroxyl groups in the molecule or an isocyanate compound (A’) derived from a diisocyanate compound (a) by converting either of the isocyanate groups into an isocyanurate ring structure with a mixture (B) of polyfunctional (meth)acrylate compounds, namely, polyhydric alcohol (meth)acrylates, which mixture comprises a polyhydric alcohol (meth)acrylate having one or more hydroxyl groups and a polyhydric alcohol (meth)acrylate wherein all the hydroxyl groups are esterified.
