Title: Paste for color filter, color filter using that and liquid crystal display device
Inventor: NOMURA AKIKO
IPC: C09D11/00
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain a paste for a color filter which hardly produces coating defects by specifying the change rate of the viscosity when a specified shear rate is applied to the paste. SOLUTION: This paste for a color filter essentially consists of pigments, polymers and solvent. The paste is prepared in such a manner that when 5 rpm shear rate is continuously applied to the paste, the change rate of the viscosity is within 5%. When a paste shows increase of >=5% in the viscosity under continuous shear, it is supposed that aggregation of pigments is accelerated in the paste to increase the viscosity. This causes problems on the coating property and the storage stability. If a paste shows decrease of >=5% in the viscosity, it is supposed that the structure of aggregation of pigments is broken by shear, and this causes problems on the coating property and the performance of a paste coating film.  In this method, the viscometer used to measure the viscosity of the paste for a color filter is not specified, and a capillary viscometer, rotating-cylinder viscometer, cone and plate viscometer or the like can be used, and especially, a cone and plate viscometer is preferably used.

Filed: 1987-12-17
Abstract: PURPOSE:To execute a character string in an external file without especially inspecting the character string by storing only the character string whose effect is confirmed by practically executing it by a console control in a data processor. CONSTITUTION:Since a key inputted character string and a response to the character string from the host side are displayed on a CRT (e), the operator can judge a character to be successively key inputted. When the key inputted character string is effective, the operator depresses a function key to be a specific key for storing the inputted character string in an external storage device. A data analyzing part (b) receives a control code indicating the output of the external storage device and outputs the contents of an input data buffer indicated by an old input data buffer pointer c2 to a disk (g), so that only the character string recognized at its effectiveness by practically executing it is stored in the disk (g).
