Abstract: The present invention provides stable, quick drying aqueous compositions useful in making traffic markings having excellent low temperature flexibility which comprise (i) one or more vinyl or acrylic emulsion polymers chosen from single stage and multi-stage emulsion polymers, the polymer or at least one stage thereof having both a calculated glass transition temperature (calculated Tg) of from −25 to 0° C., and a calculated Hansch parameter of 1.4 to 2.25, and (iii) one or more fillers, extenders and/or pigments, wherein the composition has a percent pigment volume concentration (% PVC) of from 50 to 80% and, preferably, a volume solids of from 50 to 75%. The compositions may comprise one or more silanes, and one or more polyamines and a volatile base, such as ammonia.

Abstract: The present invention provides aqueous polymer compositions containing one or more, or, preferably, two or more markers selected from a C1-C12 alkyl phenyl ether having a formula Ph(R2)m(OR1)r, wherein Ph is an aromatic ring containing group having from six to nine carbon atoms, R1 is a C1-C12 alkyl group, R2 is a C1-C12 alkyl group, m is an integer of from 0 to 5, n is an integer of from 1 to 3, and (m+n) is an integer of from 1 to 6. The markers are readily detectable, such as by mass spectroscopy, upon solvent extraction and separation from the aqueous polymer compositions, or from dried or cured coatings, film or layers thereof.
