Definitions

• the present invention relates to a carbonate (meth)acrylate composition.
• (Meth)acrylic monomers with carbonate groups are known to have high polarity and high cohesion derived from carbonate groups.

• Patent Document 2 a method of reacting an epoxy compound with carbon dioxide is known, and it has been reported that a (meth)acrylic monomer having a carbonate group produced by this method is colorless and transparent.
• (meth)acrylic monomers with carbonate groups have excellent transparency and adhesion, but on the other hand, there is a problem of denaturation of these carbonate group-containing monomers at high temperatures. For example, during transportation, the temperature may exceed 40° C. depending on the storage conditions in summer, etc. At this time, denaturation of the monomer occurs. Specifically, a (meth)acrylic monomer having a carbonate group stored at a high temperature of 40° C. or higher undergoes significant coloration, although the purity does not change significantly before and after storage. Since this coloring is a hindrance to hue adjustment in paint applications requiring transparency, the development of a (meth)acrylic monomer having a carbonate group that is resistant to coloring during storage has been expected.
