PRESSURE SENSITIVE ADHESIVE BASED ON AN EMULSION OF LATEX RESISTANT TO WHITENING WITH WATER AND ITS PRODUCTION.

摘要

A laminate consisting essentially of: (a) a separable liner, (b) a printing face, and (c) a pressure sensitive adhesive between and adhering the separable liner and the printing face, which comprises a latex emulsion aqueous with an average particle size diameter less than or equal to 100 nm prepared from a mixture of monomers consisting essentially of: i) at least one alkyl acrylate having at least 4 carbon atoms in the alkyl group, ii) at least one ethylenically unsaturated carboxylic acid or its corresponding anhydride, and iii) a styrene monomer, a hard monomer with a Tg 30 ° C, or mixtures thereof emulsified in the presence of an emulsifier consisting essentially of ** see image * * where, R1 is an alkyl, alkenyl, or aralkyl group containing between 6 and 18 carbon atoms, R2 is H or R1, R3 is H or a propenyl group; A is an alkylene group of 2 to 4 carbon atoms, N is an integer ranging from 1 to 200, and M is an alkali metal, an ammonium ion or an alkanolamine cation.
