| 摘要 |
The present invention is a curable resin composition comprising a copolymer (A) represented by the following general formula (1), silica fine particles (B), a reactive monomer (C) and a polymerization initiator (D). In the general formula (1), X is an atomic group formed by removing "k" mercapto groups from a multifunctional thiol compound having at least "k" mercapto groups; Y is a monovalent organic group derived from a copolymer formed by copolymerizing unsaturated monomers; and "k" is an integer of 3 to 10. The present invention can provide a hard coat agent which has low curing shrinkage and which has both low curing shrinkage and antiblocking properties as needed; a hard coat film and a hard-coat treated plastic substrate having high pencil hardness and low curling properties, by using this hard coat agent.
