MARKER COMPOSITION FOR SKIN

A marker composition suitable for skin may use a dye with good color development, which is capable of preventing color separation and also preventing absorption of the dye into the skin or the like. Such a marker composition may contain at least 1 to 5 mass % of an acid dye, an aminoalkyl (meth)acry...

Beschreibung
Zusammenfassung:	A marker composition suitable for skin may use a dye with good color development, which is capable of preventing color separation and also preventing absorption of the dye into the skin or the like. Such a marker composition may contain at least 1 to 5 mass % of an acid dye, an aminoalkyl (meth)acrylate copolymer, a water-soluble organic solvent, and water. The pH may be lower than 7.0. The aminoalkyl (meth)acrylate copolymer may be a copolymer polymerized from monomers selected from Group A (ethyl (meth)acrylate, methyl (meth)acrylate, n-propyl (meth)acrylate, and the like) and from Group B (2-(dimethylamino)ethyl (meth)acrylate, 2-(diethylamino)ethyl (meth)acrylate, and 3-(dimethylamino)propyl (meth)acrylate) respectively, and a ratio of the monomer of the group B may be 2 to 20 mass % in the copolymer.
