primer composition

摘要

One embodiment of the present invention relates to a primer composition, a primer coating film, a laminated antifouling coating film, a method for producing a substrate with a primer coating film, or a method for manufacturing a substrate with a laminated antifouling coating film, the primer composition comprising an olefin resin (A) and a piece. It contains a normal pigment (B) and satisfies any one of conditions 1 to 3 below. Condition 1: The primer composition contains an organic solvent immiscible with water, the average particle diameter of the pigment (B) is 25 ㎛ or more, and the content of the pigment (B) is 17% with respect to 100% by mass of the solid content of the primer composition. mass% or more Condition 2: The primer composition contains an organic solvent immiscible with water, the average particle diameter of the pigment (B) is less than 25 ㎛, and the content of the pigment (B) is 42% with respect to 100% by mass of the solid content of the primer composition. mass% or more Condition 3: The primer composition contains water, the resin (A) is a water-based resin, and the content of the pigment (B) is 50% by mass or more with respect to 100% by mass of the solid content of the primer composition.
