摘要： To provide a papermaking internal sizing agent capable of efficiently imparting sizing performance even in neutral papermaking which uses calcium carbonate as filler, and uses no aluminum sulfate or uses a small amount of aluminum sulfate, and also provide a paper or a paperboard obtained by using the papermaking internal sizing agent. The papermaking internal sizing agent comprises as an effective ingredient an amphoteric copolymer having hydrophobic groups and cationic groups, at least a part of the cationic groups being quaternized. Preferably, the amphoteric copolymer is obtained by polymerizing monomer ingredients that it essentially contain a hydrophobic monomer (A), a cationic monomer (B), and an anionic monomer (C) and that an anion equivalent of the monomer (C) is 0.1 to 90% of a cation equivalent of the monomer (B), in which a rate of quaternizing of the cationic groups is not less than 40% by mole. The paper or the paperboard contains the above papermaking internal sizing agent.

摘要： To effectively impart sizing performance to paper, while reducing the amounts of an internal sizing agent and aluminum sulfate, the invention provides as a papermaking additive a mixture of a cationic copolymer having a hydrophobic group whose quarterization ratio is 40% by mole or more, or an amphoteric copolymer having a hydrophobic group which has the same quarterization ratio as above, and in which the ratio of the anion equivalent to the cation equivalent is 0.1 to 90%, and a filler (a pretreated filler). The pretreated filler is one in which suitable water repellency is imparted to the filler. Hence, by adding this to pulp slurry, followed by a wet papermaking, the pretreated filler is efficiently adsorbed onto pulp fibers having anionic property, so that effective sizing performance can be imparted to the paper by using a smaller amount thereof than the internal sizing agent, while reducing the amounts of the internal sizing agent and the aluminum sulfate.

摘要： A disk substrate is supported by a support base formed on a center pin which is vertically movable on a selective basis, a table is set below the disk substrate, and a stamper is positioned on the table by means of a guide ring or the like. A ring-shaped portion of resin which is cured upon radiation of ultraviolet rays is set on the stamper. The center pin is then caused to descend by means of a drive mechanism, to a first position, at which position the disk substrate is on the point of contact with the resin. Then, the disk substrate is caused to descend intermittently in units of very small amounts, to a second position, at which position the entire periphery of the ring-like resin is brought into contact with the disk substrate. From the second position, the disk substrate is made to descend by means of the a load of a weight while, at the same time, the ring-shaped portion of resin is drawn by vacuum suction from its central position, thereby forming on the surface of the stamper a resin layer on which a record, formed on the stamper, is imprinted.
