An aqueous coating agent composition includes (A) a curable resin in the form of an aqueous emulsion, (B) a surfactant, (C) solid particles, (D) one or more nitrogen-containing heterocyclic compounds, and (E) water. In various embodiments, component (C) includes a solid lubricant, and for reasons of environmental regulations, component (D) includes 1,3-dimethyl-2-imidazolidinone.

The present invention relates to a lubricating composition for an engine, in particular for a motor vehicle engine, comprising at least one base oil and at least one compound able to release formaldehyde under the temperature and pressure conditions of the combustion chamber of the engine.

It also relates to the use, in a lubricating composition intended for an engine, of a compound able to release formaldehyde under the temperature and pressure conditions of the combustion chamber of the engine, as an additive for preventing and/or reducing pre-ignition, in particular low-speed pre-ignition (LSPI).

A composition for sliding member includes a binder resin, a solid lubricant, and an epoxy modified silicone oil having an epoxy group at both ends or at one end thereof. A weight ratio of the binder resin and the epoxy modified silicone oil is 97:3 to 75:25.
