Semi-cured product, cured product and method for producing these, optical component, curable resin composition, and compound

摘要

A curable resin composition containing a compound of formula (1), a compound of formula (2) and a thermal- or photo-radical polymerization initiator is capable of producing a cured product having a low Abbe's number and capable of realizing burr reduction in molding the composition. Ar1 to Ar4 represent aryl or heteroaryl, at least one of Ar1 to Ar4 is aromatic condensed ring, and two or more of Ar1 to Ar4 have a polymerizable group, and at least one of R21 to R26 forms a ring, or at least two bond to each other to form a ring:;

1. A curable resin composition containing a condensed ring-containing compound represented by the following general formula (5), a non-conjugated vinylidene group-containing compound represented by the following general formula (2), and at least one of a thermal- or photo-radical polymerization initiator: wherein in the general formula (5), Ar11 and Ar12 each independently represent an aryl or heteroaryl group containing the benzene ring surrounded by the broken line, Ar13 and Ar14 each independently represent an aryl or heteroaryl group containing the benzene ring surrounded by the broken line, and at least one of Ar13 and Ar14 is an aromatic condensed ring group containing the benzene ring surrounded by the broken line as one condensed ring therein, L1 to L4 each independently represent a single bond, an oxygen atom or a sulfur atom, R5 to R8 each independently represent a single bond or an alkylene group optionally having a substituent, L5 to L8 each independently represent a single bond, an ester bond, a thioester bond or an amide bond, and R9 to R12 each independently represent a hydrogen atom or a methyl group, a and b each independently indicate an integer of from 1 to 5, and c and d each independently indicate an integer of from 0 to 5, R1 to R4 each independently represent a substituent, e, f, g and h each independently indicate an integer of 0 or more, the upper limit of e and f each is 5-a and 5-b, respectively, the upper limit of g and h each is a value calculated by subtracting c or d from the possible maximum number of the substituents that Ar13 and Ar14 each may have, provided that in a case where Ar13 and Ar14 each are an aromatic condensed ring group containing the benzene ring surrounded by the broken line as one condensed ring therein, the structures surrounded by c's or d's parentheses as well as R3 and R4 each may independently substitute on the benzene ring surrounded by the broken line or on any other ring than the benzene ring surrounded by the broken line; wherein R21 to R26 each independently represent a substituent, at least one of R21 to R26 forms a ring, or at least two bond to each other to form a ring.
