摘要:
A self-exposing imaging element is disclosed comprising a support member, a light sensitive layer, and a layer containing reagents which will chemically react in a chemiluminescent reaction to produce light which exposes the light sensitive layer when in contact with an original. Reagents in the light generating layer are physically or chemically segregated prior to exposure to prevent reaction, for example, by encapsulation of one of the reactants, the reaction solvent, or a catalyst. To copy the self-exposing imaging element is placed in contact with an original, the light generating layer is activated by causing the reactants to mix or introducing the reaction solvent or catalyst and the radiant energy generated produces an image of the original in the radiation sensitive layer by reflex imaging or direct transmission imaging.
摘要:
A process for the production of a hot melt coating composition containing microcapsules. The process comprises the steps of preparing a dispersion of substantially discrete microcapsules in a volatile solvent continuous phase. A hot melt suspending medium is prepared, the hot melt suspending medium having a melting point of from about 50.degree. C. to about 140.degree. C. and a melting point range of less than about 15.degree. C., the hot melt suspending medium being in a fluid state. The dispersion of substantially discrete microcapsules in a volatile solvent is then mixed with the fluid hot melt suspending medium with turbulent agitation to form an intimate mixture of the dispersion of microcapsules and the hot melt suspending medium. Heat and a vacuum are applied to the mixture, while maintaining the agitation, until the volatile solvent is substantially removed from the mixture to form a dispersion of substantially discrete microcapsules in the liquid hot melt suspending medium. The heat is applied at a rate sufficient to maintain the mixture at a temperature above the melting point of the hot melt suspending medium, the temperature also being above the boiling point of water at the vacuum level.
