Curable resin composition, transparent laminate, and process for producing transparent laminate

A curable resin composition comprising:

• unsaturated urethane oligomer (A):
• an unsaturated urethane oligomer having from 2 to 3 curable functional groups as mentioned below, on average per molecule, which is a reaction product of the following polyol component (A1), a polyisocyanate (A2) and the following unsaturated hydroxy compound (A3), or a reaction product of the following polyol component (A1) and an unsaturated isocyanate (A4) having the following curable functional group,
• polyol component (A1):
• a polyol component comprising the following polyol (a1),
• polyol (a1):
• a polyoxyalkylene polyol having a hydroxy value of from 15 to 30 mgKOH/g and an oxyethylene group content of from 8 to 50 mass % in the total oxyalkylene groups of 100 mass %, which is obtained by reacting a monoepoxide having at least three carbon atoms and ethylene oxide with an initiator having from 2 to 4 active hydrogen atoms on average,
• unsaturated hydroxy compound (A3):
• a compound having the following curable functional group and a hydroxy group, and
• curable functional group:
