摘要： PURPOSE:To obtain the subject paper having excellent cold ink setting property, color reproducibility and clarity and suitable for color printing by coating a base paper produced from waste paper with a specific pigment and adhesive, drying the coating layer and finishing with a calender. CONSTITUTION:A base paper having a dynamic wettability value of from -0.32 to +0.20g is produced from waste paper containing >=10wt.% of regenerated pulp produced by deinking waste OA paper, art paper, etc., with a surfactant- based deinking agent under mechanical agitation while applying compressive force. The paper is coated with a coating liquid produced by compounding an adhesive (e.g. casein and soya protein) to a pigment produced by mixing 10-90wt.% of kaolin and 90-10wt.% of an irregularly shaped pigment having an average particle diameter of >=0.5mum. The coating layer is dried and calendered preferably at 20-350 deg.C to obtain the objective paper having an air diffusibility of

摘要： PURPOSE:To ensure that manhours can be saved and at the same time, color contamination of the rear of a transfer sheet during handling can be prevented by adding a specific amount of a color developer for a total pulp volume in a support of the transfer sheet and forming an alteration-proof recorded image on the rear of the transfer sheet at the same time as recording of data on the front of the sheet. CONSTITUTION:The 0.2 to 10wt.%, preferably 0.5 to 8wt.% of a color developer for the total pulp volume should be ensured as a ratio. Therefore, various fillers, sizing agents, yield improvers or sheet strength enhancers to be added, if necessary, as sheet making internal addition assistants are added to pulp slurry, after these materials are blended and adjusted using various adjustment devices, the blend is dehydrated and dried using a sheet making machine. The organic color developer of various color developers is superior to the inorganic color developer in terms of qualitative deterioration due to aging such as humidity resistance and lift fastness in a print color development part. For this reason, the former is recommended for use compared to the latter. A transfer sheet 1 is obtained by applying a solution of a microcapsule containing a coloring agent and oil to the rear of support containing a color developer. An application liquid for the color developer layer 6 is applied to the support such as high-quality sheet or coated sheet and finished as a pressure-sensitive sheet 2 for sheet reception(background sheet).

摘要： PURPOSE:To enhance smoothness while keeping the gap properties of an intermediate layer by forming the intermediate layer by applying a coating solution containing predetermined pigment and passing the same through a pressure nip so as to set the positive reflection smoothness of the surface of the intermediate layer to a predetermined value or more to apply calendar processing thereto. CONSTITUTION:An intermediate layer is formed by applying a coating solution containing pigment whose oil absorbancy according to JIS K-5101 is 100cc/100g or more and passed through the pressure nip constituted of an elastic roll and a metal roll heated to 80 deg.C or higher so as to set the positive reflection smoothness of the surface of the intermediate layer to 40% or more to be subjected to calender treatment. As the pigment, for example, one having specific oil absorbancy such as baked clay, aluminum oxide or titanium oxide and inorg. or org. pigment prepared by physically or chemically treating general pigment so as to provide the above mentioned specific oil absorbancy thereto are used. When the temp. of the metal roll is 80 deg.C or high, the surface of the intermediate layer is plasticized to a degree easily receiving smoothing action even under relatively low linear pressure and, therefore, the reduction of the void ratio in the intermediate layer is suppressed and a thermal recording material having high sensitivity and imparting high image quality is obtained.
