Material to be recorded

Abstract

Abstract PURPOSE:To form a high-performance material to be recorded both for a general use and for an ink jet recording which has a rapid ink absorption and forms a sharp image superior particularly in dot shape even with a thin coating layer, by a method wherein a coating layer containing a porous pigment is formed on a substrate having voids, filler content, and Steckigt sizing degree of specific values respectively. CONSTITUTION:A coating layer containing a porous pigment is formed on a substrate with voids of 50% of less, a filler content of 10% or more as an ash content, and Steckigt sizing degree of 5sec or less. A pulp with Schopper freeness of 40 deg. SR is desirably used. As the filler, clay, talc, titanium, plastic pigment, calcium carbonate, silica, etc. are used; the calcium carbonate is prefer able because it imparts a good to shape and minimizing a discoloration of a printed matter. In addition, the use of commonly used sizing agent, yield improver, paper strength reinforcing agent, etc. is allowed within the scope of the invention. Forming of the coating layer containing the porous pigment can further improve the dot shape, resolving power, and color properties.
