Abstract
Provided is a curable resin composition which can be cured to form a material (cured product) that has low tack properties and resists adhesion of garbage. The present invention provides a curable resin composition comprising polysiloxane (A) having not less than 2 alkenyl groups in the molecule and polysiloxane (B) having not less than 2 hydrosilyl groups in the molecule, wherein (T+Q)/D>0.3 and M+D+T+Q=1 are satisfied regarding all silicon atoms contained therein, the amount of the hydrosilyl groups with respect to 1 mol of aliphatic carbon-carbon double bonds present therein is 0.9 to 5.0 mol, and a cured product of the curable resin composition exhibits a separation strength of not more than 0.40 N per mmin separation load evaluation and/or a total separation load of not more than 0.018 N·mm per mm.
