Photocurable composition, cured product and process for producing the same

A photocurable composition comprising the following components A, B and C (with the proviso that the proportion of the various components each are represented relative to 100 parts by weight of the sum of the weight of the components A and B):

• Component A:
• 70 to 99 parts by weight of an alicyclic skeleton-containing bis(meth)acrylate represented by the general formula (I):
• 22
• (wherein R1 and R2 each independently represent a hydrogen atom or methyl group;
• m represents 1 or 2;
• n represents 0 or 1;
• and p and q each independently represent 0, 1 or 2);
• Component B:
• 1 to 30 parts by weight of an alicyclic skeleton-containing mono(meth)acrylate represented by the general formula (II):
• 23
• (wherein R3 represents a hydrogen atom or methyl group;
• m represents 1 or 2;
• n represents 0 or 1;
• and r and s each independently represent 0, 1 or 2);
• and
• Component C:
• 1 to 10 parts by weight of a mercapto compound having a functionality of at least two.
