Abstract:
An aqueous polyolefin resin dispersion comprising a polyolefin resin, a basic compound and an aqueous medium, whereinthe polyolefin resin comprises a copolymer of an unsaturated carboxylic acid or an anhydride thereof, an ethylenic hydrocarbon and a specific compound, wherein the specific compound is at least one of compounds represented by the following formulae (I) to (IV): wherein R1 is a hydrogen atom or a methyl group, R2 is an alkyl group having a carbon number of not greater than 10, and R3 is a hydrogen atom or an alkyl group having a carbon number of not greater than 10, the proportion of the unsaturated carboxylic acid or the anhydride thereof in the copolymer is not smaller than 0.01 wt % and smaller than 5 wt % on a weight basis, wherein the weight ratio of the ethylenic hydrocarbon and the specific compound in the copolymer is (ethylenic hydrocarbon)/(specific compound)=55/45 to 99/1 (wt %), the aqueous polyolefin resin dispersion comprises virtually no nonvolatile water-compatibilizing agent, and the polyolefin resin is dispersed in the aqueous medium as having a number average particle diameter of not greater than 1 &mgr;m.
