PURPOSE:To obtain the titled single substance pressure sensitive recording sheet for copying paper and the like, wherein a specified amount of pulp powder, whose weight averaged fiber length is limited is included in a homogeneously mixed liquid of microcapsules including a color former and a coloration agent, coloring stain is avoided, and recording and printing compatibility is improved. CONSTITUTION:The simple substance pressure sensitive recording sheet wherein the pulp powder, whose weight averaged fiber length (TAPPI standard T232, SU-68) is 20-80mu, is included in the homogeneously mixed liquid of the microcapsules including the color former and the coloration agent (e.g. activated clay and the like). The ratio is 40-200pts. of the pulp powder with respect to 100pts. of the microcapsules (weight; converted into the solid state component). The sheet is formed by applying said homogeneously mixed liquid including said pulp powder to a supporting body (paper, sythetic film, and the like). |
