| abstract |
The calcium carbonate particles of the present invention are coated on their surface with (1) a fatty acid mixture comprising (1A) at least one of saturated fatty acids and salts thereof and (1B) at least one of unsaturated fatty acids and salts thereof, the (1A):(1B) weight ratio being in the range of 30:70 to 70:30, and (2) an organic compound such as a phthalic ester. The calcium carbonate particles of the invention easily disperse in the resin and other components that constitute an adhesive composition, and impart excellent viscosity stability and highly improved adhesion to the resulting adhesive. |
