Abstract: 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.

Abstract: 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.
