Abstract
The present invention relates to an emulsion type adhesive applicable for over-laminating films, the preparation and the use thereof. The emulsion type adhesive comprises: (a) 60 to 99.5 parts per hundred of monomers of one or more alkyl acrylates containing 4-12 carbon atoms on the alkyl group; (b) 0.5 to 40 parts per hundred of monomers of an alkyl acrylate containing 1-3 carbon atoms in the alkyl group or an alkyl methacrylate containing 1-6 carbon atoms in the alkyl group; (c) 0.1 to 5 parts per hundred of monomers of dicarboxylic acids; (d) 1 to 5 parts per hundred of a reactive surfactant; (e) 0.1 to 15 parts per hundred of an organic acid vinyl ester; and (f) 100 parts per hundred of soft water, (a) and (b) are 100 parts by hundred, while (c), (d), (e) and (f) are calculated based on the total weight of (a)+(b). The products of this invention have excellent properties.
