  • UV-CURABLE COMPOSITIONS COMPRISING CLEAVAGE TYPE PHOTOINITIATORS
    Publication number: 20210301157
    Abstract: The present invention is drawn to UV-curable ink and coating compositions comprising cleavage type photoinitiators and acids. The acids may be inorganic or organic acids, or acids generated by a photoacid generator during UV-cure. Incorporation of the acids into the UV-curable ink and coating compositions results in a reduction of migratable photodecomposition products that are produced by cleavage type photoinitiators during UV-cure. The ink and coating compositions are particularly useful for use in applications that require low migration of low molecular weight materials, such as, for example, food packaging.

  • Chlorinated copper phthalocyanine pigments
    Patent number: 11059978
    Abstract: It is an object of the present technology to overcome the disadvantages of conventional chlorination of a copper phthalocyanine which produces copper phthalocyanine, wherein the number of chlorines is less than than or equal to 4. The pigments described herein contain less chlorine than standard commercial grades of tetrachlorinated (or greater) copper phthalocyanine pigments while achieving similar color space, chromaticity, fastness properties, and color travel in automotive waterborne and solvent borne systems. The inventive pigments are more advantageous from a toxicity and environmental perspective, and allow the manufacturer to produce pigments in a safe and economical manner.
