Filed: 1994-06-24
Abstract: PURPOSE:To shorten a time for measurement of the amount of color shift and to simplify an operation therefor by a method wherein a pattern composed of a plurality of lines arranged at prescribed intervals is printed in each color and the amount of color shift is determined on the basis of a difference in the position of an overlapping part of corresponding lines of the patterns in a pair with each other and a difference in the width thereof. CONSTITUTION:Three pseudo-squares different from one another are formed of patterns of yellow, magenta and cyan, with segments made overlap, around the center CN of the patterns at four corners of printing paper, and a pattern P2 for determination of the amount of color shift thus formed is printed. Each color pattern is constructed of longitudinal lines KY1 to KY6, KM1 to KM6 and KC1 to KC6 and lateral lines L Y1 to LY6, LM1 to LM6 and LC1 to LC6 which are formed at prescribed pitches. The amount of the color shift is determined on the basis of a difference in the position of an overlapping part of discrete segments and a difference in the width thereof.

IPC: C09D11/38
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain a recording ink having properly dispersed carbon black and excellent storage stability of ink, capable of stably providing an excellent image, by using improved carbon black as a colorant. SOLUTION: This ink is obtained by dispersing carbon black containing a functional group which is generated by the decomposition of a free radical generator composed of a peroxide polymer and is linked to the surface by chemical bond into a water-based medium (preferably water or a water-soluble organic solvent such as methyl alcohol, ethyl alcohol or the like). The free radical generator comprises preferably a peroxide polymer having a structure of formula I [(P) is a group of formula II ((m) is an integer of 1-6; Ar is an aryl) or the like]. For example, a polymer obtained by reacting 3,3'- bischloromethyl-benzoyl peroxide with styrene, etc., can be used as the peroxide polymer. When the polymer is decomposed, a functional group of formula III is generated and bonded to the surface of carbon black.

Title: Formation of carbon film by high-frequency plasma cvd method
Inventor: NAKAYAMA MASATOSHI
IPC: C30B29/04
Filed: 1990-06-04
Abstract: PURPOSE:To control the hardness of a formed carbon film to the desired value by properly varying negative DC voltage on a substrate electrode independently of AC or high-frequency power for reaction excitation. CONSTITUTION:Bias voltage is impressed on a substrate electrode independently of RF power for reaction excitation, bias voltage is increased so as to make power to a substrate negative to a power supplying electrode. The diffusion of cations in plasma generated from H2 or CH4 as starting material to the outside of the substrate is inhibited by a bias electric field and the speed of the cations is increased. Accordingly, the amt. of the starting material fed to the surface of the substrate is increased and the rate of film formation is increased. Since cations provided with high translation energy by acceleration under bias voltage in the plasma collide against the substrate, C-C bonds are increased in place of CH2 and CH3 groups to increase the density and hardness of a formed film.
