Abstract: The invention relates to agents for the surface treatment of flat insulating materials having a base of aromatic polyamides, and to a method for improving the surface characteristics of such flat insulating materials. According to the invention, such agents have the structure ##STR1## where at least one of the radicals R.sub.1 to R.sub.3 has a reactive group which can be incorporated into an impregnating resin system. Advantageously at least one of the radicals R.sub.1 to R.sub.3 has a reactive hydrogen atom or has an ethylenic or acetylenic unsaturated grouping.

Abstract: Lubricants for lacquered wires are provided comprising compounds of the type A-C-B, which compounds at room temperature have an ointment or soap-like consistency, wherein A is a chemical grouping containing reactive groups which permit chemical incorporation in a polymerizable impregnating resin system, B is a saturated or unsaturated aliphatic hydrocarbon radical, and C is a binding member in the form of a carbon, nitrogen, oxygen, or sulfur grouping.The lubricant is advantageously a 2,4-dienoxy-6-aminoalkyl (-ene)-s-triazine, particularly 2,4-dienoxy-6-aminostearyl-s-triazine. Such triazines are also useful according to another embodiment of the invention as lubricants for wire with enamel insulation.
