The invention provides a color matching agent with good storage performance, low-temperature photographic fixing performance and small grey mist. Besides, the invention also provides the color machine agent with low cost and good productivity. The color matching agent used for developing static images is made from a material containing bonding resin, a colorant agent and an inorganic filler. The inorganic filler is selected from calcium carbonate, kaolin, talc, barium sulfate and the like. The color matching agent is characterized in that the glass-transition temperature of the color matchin agent is in a range of 50 to 58 DEG C and the content of the inorganic filler is 1 to 10 parts by weight relative to 100 parts of color matching agent by weight. A part of the inorganic filler is on the surface of the matrix particles of the color matching agent. The proportion of the inorganic filler on the surface of the matrix particles of the color matching agent is in a range of 5 to 40% relative to the content of the inorganic filler. |
