The present invention relates to an agricultural film (AF) comprising at least one copolyamide, wherein the copolyamide has been prepared by polymerizing at least one lactam and a monomer mixture (M). The present invention further relates to a process for producing the agricultural film (AF) and to the use of the agricultural film (AF) as mulch film, as silage film, as greenhouse film or as silo film.

A flexible polyamide film obtained by forming a polyamide including a unit formed from an aliphatic dicarboxylic acid (A1) having 18 or more carbon atoms and/or a unit formed from an aliphatic diamine (B1) having 18 or more carbon atoms, wherein the polyamide has a total content of 10 to 92% by mass of the unit formed from (A1) and the unit formed from (B1), and the film has a melting point of 240° C. or higher.

An anti-settling agent composition for aqueous coating materials, comprising [A] a polyamide which is obtained by polymerizing a diamine having 2-12 carbon atoms and an excess amount, relative to diamine, of either a dicarboxylic acid having 4-36 carbon atoms or a mixture of a dicarboxylic acid having 4-36 carbon atoms and a monocarboxylic acid having 2-22 carbon atoms, and [B] a hydrophobic organic compound which is a hydrocarbon modified with 1-3 hydroxyl groups and/or carboxyl groups and having 10-54 carbon atoms, and which has a freezing point of 20° C. or less or does not have a definite freezing point. The anti-settling agent is able to be easily dispersed in a coating material even if directly added into the coating material without being diluted when added into the coating material, and which imparts the coating material with excellent anti-settling properties.
