  • Pigmented compositions and methods for producing radiation curable coatings of very low gloss
    Patent number: 5585415
    Abstract: Very low gloss finishes are attained in pigmented, radiation curable coatings by inclusion of a combination of photoinitiators having an acylphosphine oxide photoinitiator and a second photoinitiator such as an acetophenone derivative. In the method of producing the low gloss finishes, the coating is first exposed to ionizing radiation (e.g., electron beam) in air, then exposed to actinic radiation (ultraviolet light) in an essentially inert atmosphere. The low gloss is achieved by a fine, uniform surface wrinkling effect.
