Abstract: A release coating composition for tapes is provided. The release coating composition includes: (a) 75-95 part per hundred (phr) alkyl (meth)acrylate type monomer; (b) 5-15 phr hydroxy alkyl (meth)acrylate type monomer; (c) 1-5 phr unsaturated carboxylic acid type monomer; (d) 0.1-5.0 phrunsaturated crosslinkng type monomer, and (e) 5-20 phr protective colloid. The sum of the alkyl acrylate type monomer (a), the hydroxy alkyl (meth) acrylate type monomer (b), the unsaturated carboxylic acid type monomer (c), and the unsaturated crosslinkng type monomer (d) amounts to 100 phr. The phrs of the protective colloid (e) are computed based on the sum of the alkyl (meth)acrylate monomer, the hydroxy alkyl acrylate type monomer, the unsaturated carboxylic acid type monomer, and the unsaturated crosslinking type monomer.

Abstract: The invention relates to a composition of an emulsion type, acrylic, pressure sensitive adhesive, which includes (a) 15 to 35 parts per hundred of dialkyl dicarboxylate, (b) 15 to 35 parts per hundred of vinyl esters, (c) 35 to 65 parts per hundred of alkyl acrylates or alkyl mathacrylates; (d) 0.1 to 2.0 parts per hundred of cross-linker based on the total weight of (a)+(b)+(c), (e) 0.2˜2.0 parts per hundred of hydroxy alkyl acrylates or hydroxy alkyl mathacrylates, (f) 0.1 to 1.0 parts per hundred nonionic surfactant, (g) 0.4 to 3.0 parts per hundred of anionic surfactant, (h) 0.1˜0.5 parts per hundred of reactive surfactant; which react with de-ionized water, an initiator and a buffer. The adhesives composition has excellent water-whitening resistance and aging resistance properties.

Abstract: A process for preparing an aqueous gel which comprises mixing a water-soluble acetoacetylated high molecular compound, a cross-linking agent and water, thereby cross-linking said high molecular compound to form an aqueous gel. According to the process of the invention, an aqueous gel having excellent transparency and small serum-separation, can be prepared at room temperature by only mixing. Also, according to the present invention, there are provided the aqueous gel composition containing perfume or deodorant, and the lubricant and the method for use thereof, which utilizes the process of claim 1.

Abstract: A dispersion of solvent-suspendible pressure sensitive adhesive particles, which comprises (A) pressure sensitive adhesive particles comprising an internally cross-linked copolymer and having a particle size of 5 to 200 microns and an organic solvent; the copolymer being prepared by copolymerizing(a) 2 to 10% by weight of at least one member selected from the group consisting of methyl acrylate, styrene and a methacrylate of alcohol having 1 to 5 carbon atoms,(b) 98 to 90% by weight of at least one member selected from the group consisting of a acrylate of alcohol having 2 to 12 carbon atoms and a methacrylate of alcohol having 6 to 12 carbon atoms;(c) 0.1 to 2.0% by weight of maleic anhydride, and(d) 0.05 to 1.

Abstract: A synthetic resin emulsion containing an acetoacetylated polyvinyl alcohol as a protective colloid, which has improved properties such as water resistance, freeze-thaw stability, stability at low temperatures, adhesive property and high viscosity even in low solid content. The emulsion is useful for various purposes such as adhesive, paper treating agent, paint, fiber and textile treating agent and cement modifier.
