    • PURPOSE:To obtain the subject composition having excellent abrasion resistance, heat resistance, low temperature resistance, etc., by mixing a specified base oil with a synthetic hydrocarbon oligomer, an Li salt of stearic acid, and a surface active agent containing quaternary ammonium salt groups. CONSTITUTION:Ethylene oxide and/or a plastic is made to undergo addition polymerization with a 1-18C polyhydric alcohol to give an oligomer of a molecular weight of 1,000-2,000, i.e., a base oil (a) based on a polyoxyalkylene of the formula (wherein RO is the residue of component (b); EO is an ethylene oxide residue; PO is a propylene oxide residue; m is 0-40; n is 5-45). 50-95wt.% component (a) is mixed with 0-45wt.% synthetic hydrocarbon oligomer (b) (e.g., an alpha-olefin oligomer) having a molecular weight lower than that of polyalkylene glycol, 5-30wt.% thickening agent (c) comprising an Li salt of stearic acid (e.g., lithium stearate), and 0.05-5wt.% surface active agent (d) containing quaternary ammonium salt groups (e.g., a betaine type surfactant).

    • PURPOSE: To easily produce an illumination display panel by forming louvers, which control the transmission rage of transmitted illuminating light, in light- transmissive parts of a mark part and a background part with a light- untransmissive photosensitive resin, which is applied on one face of a transparent substrate, by etching or the like. CONSTITUTION: A rectangular transparent resin plate 8 as a display panel is arranged in a front aperture part 7a of a case 7 in an instrument panel position, and a light source 9 like a lamp which illuminates this transparent resin plate 8 is arranged in the case 7. A light-transmissive mask part 10a for air conditioning indication and a light-untransmissive background part 10b are formed on the side, which is illuminated by the light source 9, of the transparent resin plate 8 by photoetching of a light-untransmissive, for example, black photosensitive resin. Plural light-untransmissive louvers 10c are formed at proper intervals in the vertical direction and in parallel on the light-transmissive mark part 10a simultaneously with photoetching.
