| 摘要 |
Thermally coalescible acrylic resin dispersions comprising particles of single-phase, surfactant-free, random acrylic polymers or copolymers, containing at least 80% by weight of acrylic units, dispersed in a surfactant-free medium that comprises a compatible liquid plasticizer that is nonvolatile at room temperature and is not a monomer of any of the polymeric components. Incorporation of a photopolymerizable, ethylenically unsaturated compound provides photosensitive dispersions useful for making relief and planographic printing plates, photoresists, and the like.
