摘要：
The present invention relates to a additive composition for use as lubricity improver for low sulphur diesel, comprising c) 0.1-10% by weight of ester derivative derived from cashew nut shell liquid (CNSL esters) of formula (I); f) 0.1-10% by weight of ester derivative derived from cashew nut shell liquid of formula (II); g) 50-95% by weight of free fatty acid of the formula RCOOH in which R represents an alkyl/alkenyl group with 12 to 24 carbon atoms. h) 1-30% by weight of synthetic esters derived by esterifying tri, tetra, penta hydric alcohols with carboxylic acids such as lauric, palmitic, linoleic, ricinoleic etc.
