LAMINATES
A method of manufacturing a laminate comprises providing a binder impregnated core layer by impregnating at least one fibrous layer with an aqueous core binder solution having a viscosity in the range 75 cP to 500 cP at a temperature of 20° C. and a bake-out solid content in the range 40 wt % to 85 wt %, in which the aqueous core binder solution comprises (i) at least 25% by dry weight of a) reducing sugar reactant(s) and nitrogen-containing reactant(s) and/or b) curable reaction product(s) of reducing sugar reactant(s) and nitrogen-containing reactant(s); and (ii) between 5% and 15% by weight of a non-aqueous solvent based on the total weight of the aqueous binder solution; providing a semi-finished assembly by assembling the binder impregnated core layer with a surface layer; and applying heat and pressure to the semi-finished assembly to cure the binder in the binder impregnated core layer and secure the core layer and the surface layer together.

TOILET PAPER
Provided is toilet paper which is excellent in thickness feeling and water disintegrability, has sufficient softness, gives a sense of security for human bodies during use, and is environmentally friendly.
Toilet paper has three or four plies. The basis weight is 12.5 to 15.5 g/m.sup.2 per ply. 80 to 100 mass % of fiber is softwood kraft pulp that is subjected to oxygen pulping and is not bleached with chlorine. The toilet paper contains a cationic fatty acid amide-based softener, and has a paper thickness of 120 to 150 μm per ply, a paper thickness of 400 to 600 μm as a whole of the toilet paper, and a water disintegrability of 10 seconds or less.
