摘要： An edible, water-soluble, thermoplastic molding composition comprising a starch material, a neutral inorganic alkali salt of protein material, water, an edible plasticizer, an edible lubricant, and other additives. This composition shows excellent moldability and processability when subjected to various constomery dry processes for molding and processing customary plastics, such as compression molding, transfer molding, extrusion molding, blow molding, inflation molding, injection molding, vacuum forming, pressure forming, heat sealing, etc. Transparent or translucent shaped articles obtained from the above composition have unique properties such as gas impermeability, solubility in water, edibility, biodegradability, etc., and may be utilized with favorable results in various fields such as food industry, feedstuff industry, agriculture, fisheries, etc. The shaped articles, if necessary, can be allowed to have any balance between its water resistance and its water-solubility by ultraviolet irradiation or by the incorporation of a protein-coagulating agent.

摘要： In preparing a dry, laminating impregnated paper or cloth by impregnating a paper or cloth with a resin solution containing a polymerization catalyst, a cross-linking monomer and, if necessary, a releasing agent, followed by drying, the use as the resin of a resin composition consisting of (A) 10 to 90 % by weight of an organic solvent-soluble diallyl phthalate prepolymer having an average molecular weight of 2,000 to 20,000 and a softening point of 70.degree. to 140.degree. C. which prepolymer has been obtained by partially polymerizing a diallyl phthalate monomer and separating and purifying the resulting prepolymer, and 90 to 10 % by weight, in total, of (B) an organic solvent-soluble non-crystalline unsaturated polyester and (C) an organic solvent-soluble benzoguanamine resin obtained by condensing in an alkaline reaction system 1 mole of benzoguanamine with 1 to 4 moles of formaldehyde, the weight ratio of (C)/(B) being up to 0.85 and the amount of (C) being at least 2 % by weight of the total weight of (A), (B) and (C), results in a stickiness-free impregnated paper or cloth. The thus obtained impregnated paper or cloth is laminated to a proper base plate, or two or more of the impregnated paper or cloth are laminated to each other, to obtain a laminate with an overlay excellent in transparency. When the above-mentioned impregnated paper or cloth is used, a laminate having a favorable gloss can be obtained even when the laminate is taken out of the press without cooling at the time of lamination.
