Claim Text:
1. A composition comprising an aqueous dispersion of a) a vinyl acetate copolymer having a T g in the range of −10° C. to 50° C. and b) a hydrophobically modified alkali soluble emulsion (HASE) comprising, based on the weight of the HASE: i) from 45 to 60 weight percent structural units of ethyl acrylate; ii) from 30 to 45 weight percent structural units of methacrylic acid; iii) from 2.0 to 20 weight percent structural units of acrylic acid; iv) from 0.1 to 5 weight percent structural units of a sulfonic acid monomer or a salt thereof; and v) from 0.1 to 10 weight percent structural units of hydrophobic macromolecular groups represented by either of the following structures: where R a is a C 8 -C 24 alkyl or aralkyl group; x+y is 10 to 100; R b and R c are each independently CH 2 CH 2 , CH 2 CH(CH 3 ), or CH 2 CH 2 CH 2 CH 2 ; R d is H or C 1 -C 6 -alkyl; and Ph is a phenylene group.
