摘要： PURPOSE:To secure a prevention of mis-transfer in a printing part and a high density of the printing by specifying an index of unevenness of film thickness in the paper making direction in a carrier consisting of resin-coated paper in which the image receiving side of a paper substrate consisting mainly of natural pulp is covered with polyethylene resin. CONSTITUTION:The heat transition type thermal transfer recording material includes paper, as a substrate, consisting mainly of natural pulp and resin-coated paper, as a carrier, having an image receiving side surface in its one side covered with polyethylene resin. On the resin-coated paper surface, an image receiving layer for heat transition type thermal transfer recording is provided. in this Instance, a carrier for the resin-coated paper is made to have an index of unevenness of film thickness set at 170mV or lower in the paper making direction. Herein, for measuring the index of unevenness of film thickness, at first, test piece is permitted to run at constant velocity between two spherical indexes to measure the fluctuation of thickness in the paper making direction. Next, the value of measuring signals is subjected to fast Fourier transformation to obtain a power spectrum by an integral addition average. Subsequently, the value of power in a specific frequency area is totalized, and then the value multiplied by 2/3 is raised to the 1/2 power.

摘要： PURPOSE:To contrive to solve a failed transferring of printing part, and ensure glossy impression by a method wherein the unevenness index of thickness in paper machine direction and center-plane mean roughness in paper machine direction in all the wavelength range are set to be below the specified values respectively in the paper as the substrate of the support concerned. CONSTITUTION:The support concerned has paper mainly made of natural pulp as substrate and one surface on image receiving side of it is covered by polyolefin resin. In this case, the unevenness index Rp of thickness in paper machine direction of the paper as substrate is set to be 1.65mV or less. Further, the center-plane mean roughness SRp in its paper machine direction in all the wavelength range measured with a tracer type three dimensional surface roughness meter is set to be 1.3mum or less. Hereupon, in order to measure the unevenness index Bp of thickness, a measuring specimen 1 is supported through a ball point 4 by an XY stage 9 so as to irradiate red LED rays 7 on the measuring specimen 1 in order to input the reflected rays in optical displacement sensors 2 and 3. After that, the input is outputted through a FFT analizer 5 into a personal computer 6.

摘要： PURPOSE:To secure the concealment of recorded contents and enable a shielding part to be easily separated to disclose the contents by disposing a pressure- sensitive recording layer, a polyolefin resinlaminated layer and a thermoplastic resin-laminated layer in order on one surface of a support and forming the shielding part so that it can be separated between both the laminated layers. CONSTITUTION:A pressure-sensitive recording sheet 7 is formed by disposing a self-color forming type pressure-sensitive recording layer 2, a first polyolefin resin-laminated layer 3 and a second thermoplastic resin-laminated layer 4 in order on one surface of a support 1. A color forming agent or a developer, both of or one of which is micro-capsulized, is singly laminated on the pressuresensitive recording layer 2, respectively, or both the agents are mixed together and applied to the layer 2. Further, white or color dyeing pigments 6 are contained in the thermoplastic resinlaminated layer 4. It is so designed that a shielding part can be separated between the first and second laminated layers 3, 4. In this way, recorded contents are reliably concealed, and, when information is disclosed, the shielding part is easily separated so that the contents can be read.
