PROBLEM TO BE SOLVED: To obtain a color developing sheet for pressure-sensitive copying which is excellent in low-temperature initial coloring properties and also in coloring density and the surface strength of a color developing layer. SOLUTION: In regard to pressure-sensitive copying recording which utilizes a coloring reaction of an electron-donating colorless dye and an electron- accepting color developing agent, the color developing layer constituted of an acrylonitrile-butadiene latex and/or an acrylic ester latex containing an electron-accepting organic compound and having a glass transition temperature of -5 to -50 deg.C is provided at least on either the surface or the rear of a substrate. |
