Abstract
Abstract Alkyd-compatible second binder resins for use in traffic paint formulations comprising copolymers containing greater than 50% by weight alkylstyrene and correspondingly less than 50% by weight alkyl acrylate exhibit good compatibility with aliphatic solvents and impart good wear properties, rapid drying and improved bead retention and reflectivity to reflectorized traffic paint formulations.
