PHOTOCURABLE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1991/011474
Kind Code:
A1
Abstract:
A photocurable resin composition comprising: (a) a modified resin prepared by the reaction of either a conjugate diene polymer having a number-average molecular weight of 500 to 5,000 and a vinyl content of at least 50 mole % or an adduct prepared from the diene polymer and an $g(a),$g(b)-unsaturated dicarboxylic acid anhydride and having a softening of 70 to 200 �C as measured by the ring and ball softening point method of JIS K 2531-60 with an $g(a),$g(b)-unsaturated monocarboxylic ester having an alcoholic hydroxyl group represented by general formula (I) to thereby effect the ring opening of at least 10 mole % of the acid anhydride groups of the adduct, wherein R�1? and R�2? each represents a hydrogen atom or a methyl group and R�3? represents a residue of a C�2? or higher hydrocarbon which may contain a heteroatom, (b) an inorganic or organic powder having a mean particle diameter of 5 $g(m)m or less, or a grafted inorganic powder prepared by grafting an (un)saturated and (un)substituted hydrocarbon residue onto an inorganic powder having a particle size of 0.1 $g(m)m or less, wherein the total number of carbon atoms of the hydrocarbon residues grafted onto one inorganic atom is 4 or above, and (c) a photopolymerization initiator.
