Document Type and Number:
WIPO Patent Application WO/2011/013720
Kind Code:
A1
Abstract:
Provided are a transparent laminate which is highly transparent and has excellent flame retardancy and a process for producing the laminate.
A curable resin composition (14) containing an unsaturated urethane oligomer (A) which has 2-4 curable functional groups per molecule on average and is a product of the reaction of (A1) a polyol ingredient that comprises (a1) a polyol having 2-3 hydroxy groups per molecule, a hydroxyl value of 35-150 mg-KOH/g, and a phosphorus atom in the molecule and has a phosphorus content of 1-7 mass%, (A2) a polyisocyanate compound, and (A3) an unsaturated hydroxy compound having the curable functional group (X) shown below and a hydroxy group is held between a pair of transparent substrates (10, 16) and is cured to obtain a transparent laminate. The curable functional group (X) is a group represented by the formula CH2=C(R)C(O)O- (wherein R is a hydrogen atom or methyl).
