Problems solved by technology

However, when a large amount of reactive diluent is used, the curability decreases and it becomes difficult to obtain sufficient physical properties of the coating film; in addition, when an organic solvent is used in combination, the risk of air pollution and fire increases
So far, reactive diluents with high diluting performance have been developed, but there is a limit to lowering the viscosity of active energy ray-curable resin compositions

Abstract

The present invention addresses the problem of providing an active energy ray-curable resin composition that can be easily water-dispersed without using a special dispersion device and can form a cured film having excellent hardness and wear resistance. The active energy ray-curable resin composition contains (A) a polyurethane (meth) acrylate that is a reactant that is a reaction component containing a hydroxyl group-containing (meth) acrylate (a1), (a2) a polyisocyanate and (a3) a hydroxyl group-containing polyalkylene glycol, and (B) a polyfunctional (meth) acrylate having a hydroxyl valueof 80-300 mgKOH / g.

Description

technical field [0001] The present invention relates to an active energy ray-curable resin composition, an active energy ray-curable aqueous resin composition, a coating agent composition, a cured film and a film. Background technique [0002] Active energy ray-curable resin compositions generally contain a reactive oligomer and a reactive diluent, are excellent in safety because they do not contain a solvent, and are also excellent in curability, so they are generally preferred from the viewpoint of productivity and energy saving. Also considered a characteristic substance. [0003] Depending on the application, the active energy ray-curable resin composition may need to be lowered in viscosity. In this case, methods such as using a large amount of reactive diluent or using an organic solvent in combination are used. However, when a reactive diluent is used in a large amount, the curability decreases and it becomes difficult to obtain sufficient physical properties of the ...
