Title: Method for removing formaldehyde in microcapsule dispersion liquid
Inventor: HIRASAWA AKIRA
IPC: B41M5/165
Filed: 1990-05-31
Abstract: PURPOSE:To prevent a dispersion liquid from becoming tacky and coloring and to prevent deterioration of microcapsule wall film by treating the microcapsule dispersion liquid in which formaldehyde remains with peroxide under an alkaline condition. CONSTITUTION:The microcapsule dispersion liquid in which formaldehyde remains is treated with peroxide under alkaline condition so as to remove harmful formaldehyde. As for the alkali compd., hydroxide of alkali metal or alkaline-earth metal, for example, sodium hydroxide is used. As for the peroxide, hydrogen peroxide is preferable, and the add amt. of peroxide ranges from the same equiv. of the residual formaldehyde to three times as the equiv. The microcapsule dispersion liquid thus treated to remove the residual formaldehyde is then adjusted to pH 7 - 8 by using an org. acid such as p-toluenesulfonic acid, oxalic acid, acetic acid, etc., or an inorg. acid. By this method, the dispersion liquid is prevented from becoming tacky and coloring, and deterioration of microcapsule wall film can be prevented.

Title: Device for producing electrolytic copper foil
Inventor: KUBO TOYOSHIGE
IPC: C25D1/04
Filed: 1990-05-31
Abstract: PURPOSE:To obtain the high-quality electrolytic copper foil uniform in thickness in the cross and longitudinal directions, by splitting an anode in its cross direction into plural foil thickness uniformizing anodes and separately controlling the quantity of electricity to be supplied to each anode. CONSTITUTION:A cathode drum 1 as a rotary cylinder is partially dipped in an electrolyte and confronted with at least one insoluble anode 3. The anode 3 on the copper foil discharge side is formed as the foil thickness uniformizing split anode 4, and an appropriate number of split anodes are formed. An electrolyte is supplied from a gap between the anodes 3 and 4 and flows through the gap between the cathode drum 1 and the anodes 3 and 4. Under these conditions, a specified voltage is maintained between the cathode drum 1 and the anode 3 by a rectifier 5. As the cathode drum 1 rotates, copper is electrodeposited from the electrolyte, and the crude foil in the specified thickness is released. In that case, a slave rectifier 7 as a means for separately controlling the quantity of electricity is connected to separately control the split anodes 4. Consequently, the thickness of the electrolytic copper foil produced is uniformized.
