NOVELTY - A curable resin composition (14) comprises unsaturated compound (A) having an average of 1.8-4 hardenable functional groups (X) per molecule, and linear or branched polyoxyalkylene chain, and phosphorus-containing unsaturated compound (B) having hardenable functional group (X) and a phosphorus atom. The phosphorus content in the curable resin composition (100 %mass) is 1-5 %mass.    USE - Curable resin composition is used for manufacturing transparent laminates (both claimed) of safety glasses, security glasses, and fire-prevention safety glasses used in buildings, windshield glasses used in motor vehicles, displays, and solar cell modules. Can also be used as photoresist.    ADVANTAGE - The curable resin composition enables manufacture of transparent laminates having excellent transparency, impact resistance, and flame retardance.    DETAILED DESCRIPTION - A curable resin composition comprises unsaturated compound (A) having an average of 1.8-4 hardenable functional groups (X) per molecule, and linear or branched polyoxyalkylene chain, and phosphorus-containing unsaturated compound (B) having hardenable functional group (X) and a phosphorus atom. The phosphorus content in the curable resin composition (100 %mass) is 1-5 %mass. Group (X) is of formula: H2C=C(R)C(O)O-.    R=H or methyl.    INDEPENDENT CLAIMS are included for the following:    (1) transparent laminate having a pair of transparent substrates (10) and a layer of cured resin composition interposed between the transparent substrates; and    (2) manufacture of transparent laminate, which involves forming a sealed space for accommodating the curable resin composition between a pair of transparent substrates in a reduced-pressure atmosphere, producing a lamination precursor having the curable resin composition sealed between the transparent substrates, placing the lamination precursor in an atmosphere where the pressure is higher than the reduced-pressure atmosphere, and hardening the curable resin composition.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view explaining the manufacturing method of transparent laminate.
