Abstract
The present invention is a polyol composition (A) for the production of polyurethane resins which comprises a compound (a1) having a vinyl-polymerizable functional group represented by general formula (I) and a strength improver (a2) represented by general formula (II). In general formula (I), R is hydrogen, C1-15 alkyl, or C6-21 aryl. In general formula (II), R1 is a residue derived from an active-hydrogen-containing compound by removing one active hydrogen atom; Y is a residue derived from an at least divalent aromatic polycarboxylic acid (f) by removing the carboxyl groups; a is an integer satisfying the relationship: 1≦a≦(the number of substituents on the aromatic ring−1); Z is a residue derived from an at least m-valent active-hydrogen-containing compound by removing the m active hydrogen atoms; and m is an integer of 1 to 10.
