More Information
Summary:Pigment pre-dispersions for use with ionomers, methods for making pigment pre-dispersions for use with ionomers, pigmented ,ionomers, and multilayer films containing pigmented ionomers are disclosed. The pigment pre-dispersions generate or maintain a minimal pigment particle size in order to optimize the dispersability of the pigment in an ionomer upon a single pass through processing equipment. The carrier of the pigment predispersion is chosen based on compatibility parameters, such as refractive index and viscosity, to be compatible with the ionomer. Carriers can include acid copolymers, acid terpolymers, ionomers, polyethylenes, ethylene vinyl acetate, and ethylene methacrylate. The pigmented ionomers created from these pigment pre-dispersions have well dispersed pigment with a particle size of less than or equal to about 25 micrometers. Films or sheets can be created from the pigmented ionomers and the pigmented ionomers can be used in mulitlayer films.
