AI Technical Summary

Technical Problem

The coating materials used in the prior art in external environments have shortcomings in durability and visibility, especially in outdoor environments that are susceptible to ultraviolet rays, wind and rain, resulting in material aging and information difficult to read.

Method used

A coating material containing a base layer, a printed portion and a surface protective layer is used, wherein the printed portion uses active energy radiation to cure the ink, the ink contains hydroxyl components and silane compounds, and the base layer and the printed portion form a reinforced connection through copolymerization reaction.

Benefits of technology

Significantly improves the outdoor durability and visibility of the coating material, prevents UV damage, and maintains clarity and readability of information.

Abstract

To provide a laminate excellent in durability and visibility in an outdoor use, and also to provide a manufacturing method of a laminate, an information management method and an information management system.SOLUTION: A laminate 1 includes a base layer 10, a printed part 12 formed on a surface of the base layer 10 and a surface protective layer 14 protecting the printed part 12. The printed part 12 is obtained through curing an active energy ray-curable ink. The active energy ray-curable ink includes (A) a hydroxyl group-containing monomer and / or a silane compound. The base layer 10 includes a curative component cross-linking to the component (A) included in the printed part 12.SELECTED DRAWING: Figure 1
