Abstract:
(EN) This binder composition contains: a binder material which contains a particulate polymer A and a readily soluble polymer B; and an organic solvent. Here, the particulate polymer A contains 1.0-10.0 mass% of ethylenically unsaturated monomer units and 30.0-98.0 mass% of (meth)acrylic acid ester monomer units. Furthermore, the particulate polymer A contains two types of particulate polymer A1 and A2 that are different in terms of volume average particle diameter. The volume average particle diameters D50A1 and D50A2 of these particulate polymers satisfy the relationship D50A2 > D50A1 ≥ 50 nm.
(FR) L'invention concerne une composition de liant contenant : un matériau liant qui contient un polymère particulaire A et un polymère B facilement soluble ; et un solvant organique. Le polymère particulaire A contient de 1,0 à 10,0 % en masse d'unités monomères à insaturation éthylénique et de 30,0 à 98,0 % en masse d'unités monomères d'ester d'acide (méth) acrylique. En outre, le polymère particulaire A contient deux types de polymère particulaire A1 et A2 qui sont différents en termes de diamètre de particule moyen en volume. Les diamètres de particule moyen en volume D50A1 et D50A2 de ces polymères particulaires satisfont la relation D50A2 > D50A1 ≥ 50 nm.
(JA) 粒子状重合体A及び易溶解型重合体Bを含む結着材と、有機溶媒を含むバインダー組成物である。ここで、粒子状重合体Aは、エチレン性不飽和酸単量体単位を1.0質量%以上10.0質量%以下、(メタ)アクリル酸エステル単量体単位を30.0質量%以上98.0質量%以下の割合で含む。さらに、粒子状重合体Aは、体積平均粒子径が相異なる2種類の粒子状重合体A1及びA2を含み、これらの体積平均粒子径D50A1,D50A2が、式:D50A2>D50A1≧50nmを満たす。
