Problems solved by technology

However, the current situation is that it is difficult to obtain a photocurable composition that fully satisfies curability, surface smoothness, strength, storage stability, etc.
[0003] Especially for toner base images such as electrophotography, when there is a fusel oil layer on the surface of the image, it is more difficult to obtain the required performance.

Abstract

The invention provides a photocurable coating composition with excellent surface smoothness, and non-sticky overprint with excellent surface smoothness by coating and solidifying the photocurable coating composition and method of producing the same. A photocurable coating composition includes an ethylenically unsaturated compound having an alicyclic hydrocarbon group and a photopolymerization initiator. There are also provided a process for producing an overprint, the process including a step of obtaining a printed material by printing on a printing substrate, a step of coating the printed material with the photocurable coating composition, and a step of photocuring the photocurable coating composition, an overprint produced by the process, use of the photocurable coating composition for producing an overprint, and use of the photocurable coating composition for producing an overprint for an electrophotographically printed material.

Description

technical field [0001] The present invention relates to a photocurable coating composition, an overprint (over-print) and a production method thereof. Specifically, it relates to a photocurable coating composition curable by irradiation with active radiation such as electron beams and ultraviolet rays. In particular, it relates to the coating of an image produced by arranging ink and / or toner on a printing base material (imaging base material) by means of flat plate, letterpress, gravure, screen printing, inkjet, electrophotography, etc. photocurable composition. More specifically, it relates to photocurable overprint compositions for coating a printed matter of a toner base printed by electrophotography. Background technique [0002] In recent years, many active radiation-curable compositions that can be used in ultraviolet-curable printing inks, paints, and coatings have been developed, and these are now widely used. However, at present, it is difficult to obtain a phot...
