Abstract: Disclosed is an ultraviolet curable/ultraviolet protective overcoating for application to heat and/or pressure sensitive record materials known to undergo degratory effects when exposed to ultraviolet radiation within a known "photodegratory" wavelength range. The overcoatings of the invention generally contain a first additive which promotes curing of the overcoating by UV radiation outside of the "photodegratory" range and a second additive which remains present within the cured overcoat and serves to absorb or otherwise prevent transmission of UV radiation within the "photodegratory" range. Additionally, the overcoatings of the invention may contain a third additive capable of acting as a free radical scavenger within the cured overcoating, thereby preventing or minimizing certain degratory effects of free radicals within or adjacent to the cured overcoating.
Abstract: An erroneously recorded image among recorded images on a recording medium is corrected by a correction sheet comprising an adhesive layer on a support. The adhesive layer is heated to develop an adhesive force and caused to adhere to the error image and peel the error image when the correction sheet is separated from the recording medium. The adhesive layer comprises a laminate structure including a separation prevention layer and an upper layer, and the separation prevention layer is in charge of cohesion strength, intimate adhesion to support and flexibility under heating of the adhesive layer. Because of the laminate adhesive layer structure, the correction sheet allows for adequate correction of an error image even on a recording medium with poor surface smoothness without causing correction failure, such as reverse transfer.
