ADHESIVE COMPOSITIONS

摘要

There is described emulsion lattices of UV-attenuating polymers adapted to form a waterborne adhesive for pressure sensitive adhesive (PSA) film and methods of making and using such lattices and laminates formed with such PSAs. Uses for this PSA include film marking and labelling. The UV attenuating polymer may be homopolymers and/or copolymers (e.g. ter-, tetra- and/or penta- polymers and/or multi­-monomer compositions) of vinyl-functionalised monomers of benzotriazoles, benzophenones, s-triazines, oxalanilides and/or mixtures thereof, for example 2-(2­-hydroxy-5-methacryloxyethyl)-2H-benzotriazole. Other additives may be added such as: thickeners, defoamers, plasticizers, wetting agents, slip and mar agents (e.g. silicones) biocides, fire retardants, pigments, dyes, and/or (at low levels) dispersants.
