摘要:
A PVA film successively oriented in two orthogonal directions is prepared by firstly elongating the film in the longitudinal direction by more than 200% while maintaining the water content (Z .times. 100)% at a value of from 10 to 35% and the temperature in a range of from (1.50/Z +20).degree. C to 75.degree. C. The film is then preheated while maintaining its water content at least 7%, and then elongated laterally by more than 200% at a temperature of from 45.degree. to 110.degree. C. Then the film is heat treated at a temperature of 110.degree. to 210.degree. C while permitting the film to shrink by less than 15% in the lateral direction. Finally, the film is cooled to room temperature under tension.

摘要:
The present invention relates to a coloring composition for preventing see-through of cloth which comprises, on the basis of the total mass of the composition, a pigment in an amount ranging from 0.002% by mass to 1% by mass; a polymer particulate dispersion; and water.The present invention can thus provide the cloth which can prevent any see-through of the color of the underlying layer without causing any color-see-through phenomenon even if the cloth is white or light-colored one, and which can show excellent fastness while maintaining hand and feel peculiar to the original cloth irrespective of the material of the cloth used. In addition, even the mixed spun cloth can be colored with only the coloring composition of the present invention according to the single-step coloring technique and the coloring method according to the present invention is quite simple and excellent in working efficiency, energy efficiency and water resource-efficiency and the method does not suffer from a problem of, for instance, any environmental pollution.
摘要:
In a ballpoint pen which is formed to have an ink-consumption value per unit area of 0.64 to 1.6 mg/cm2, the surface tension of the ink for the ball point pen is adjusted to a range of 16 to 32 mN/m so that blotting, line splitting and the like hardly occur, that the ink transferred onto the paper surface is ready to be dried and that fluctuation in the density and width of the written lines are less likely to occur due to a storage environment and to a writing condition.

摘要:
Provided is an ink composition comprising at least a colorant and water, wherein the ink composition further contains 0.5 to 15% by weight of reduced dextrin or reduced maltodextrin based on the total weight of the ink composition. It is a water based ink composition for a ball point pen which is excellent in dryout resistance and is safe and which does not cause a fluctuation in a viscosity and a pH with the passage of time.
摘要:
An apparatus for reproducing signals recorded on a selected one of first and second discs of different diameters, such as, a relatively large diameter video disc and a relatively small diameter compact disc, has a disc-transporting tray mounted for substantially horizontal movement between a first or operative position within a housing and a second or disc-inserting and withdrawing position in which the tray projects substantially forwardly from the housing through an opening at the front of the latter, the tray having first and second disc mounting portions dimensioned for receiving and holding the relatively large and small diameter discs, respectively, and the second or relatively small-diameter disc mounting portion being disposed at a front part of the tray and substantially contained within the confines of the first or large-diameter disc mounting portion for minimizing the required size of the tray, and hence the overall size of the apparatus. Further, access to the second or relatively small-diameter disc mounting portion of the tray for inserting or withdrawing a compact disc may be had when the tray is only partly projected from the housing, thereby to reduce the time required for loading and unloading or exchanging a compact disc.
