The methacrylate-based or acrylate-based monomer is to be used in the 19 ~ 80% by weight based on the adhesive resin. If the amount thereof is less than 19% by weight, the viscosity is high and the workability is deteriorated, and if the amount thereof is more than 80% by weight, the viscosity is low, the viscosity is lowered and the volatilization of the monomer is high, which is undesirable because it is hardly curable. .

The aggregate and the filler to be used in the range of 10 to 80% by weight relative to the total amount of 100% by weight of the adhesive resin. If the amount thereof is less than 10% by weight, there is a problem that the formed coating film flows down, and when the amount is more than 80% by weight, the viscosity of the adhesive composition is increased to reduce workability.

Now, mixing the curing agent into the produced subject matter can produce the adhesive composition of the present invention.

The curing agent is to be mixed in the range of 0.5 to 10 parts by weight based on 100 parts by weight of the main ingredient. Its content can be adjusted to some extent depending on temperature, season and the like.
