Stain-resistant article and use thereof

A method of using a polyamide moulding composition containing:

• (A) 30-100% by weight of a polyamide mixture, consisting of:
• (A1) 50-98% by weight of at least one semi-aromatic polyamide;
• (A2) 2-50% by weight of at least one amorphous and/or microcrystalline polyamide, different from (A1), having a glass transition temperature of at least 100° C., measured according to ISO-Norm 11357-11-2, wherein
• amorphous polyamides of the polyamide (A2) have a heat of fusion of at most 4 J/g and
• microcrystalline polyamides of the polyamide (A2) have a heat of fusion in the range of 4-25 J/g,
• in each case determined according to ISO 11 357-11-2 on the granulate, differential scanning calorimetry (DSC) with a heating rate of 20° C./min, based on:
• (a1) 20-100 mol % of at least one cycloaliphatic diamine;
• and
• 0-80 mol % of at least one other aliphatic and/or aromatic diamine;
• wherein the mol % within component (a1) supplement to 100 mol %, and
• (a2) aromatic and/or aliphatic dicarboxylic acids with at least 6 carbon atoms,
• with the proviso that up to 45 mol % of the totality of monomers of components (a1) and (a2) can be replaced by lactams comprising 6 to 12 carbon atoms or amino carboxylic acids comprising 6 to 12 carbon atoms;
• wherein the proportions (A1) and (A2) together form 100% by weight;
• (X) 0.01-20% by weight of at least one or several inorganic white pigments;
• (B) 0-70% by weight of fibrous additives (B1) and/or particulate additives (B2) with the exception of inorganic white pigments
• (C) 0-30% by weight of polymers different from (A)
• (D) 0-25% by weight of a flame retardant
• (E) 0-3% by weight of additives;
• wherein the sum of the constituents (A)-(E) makes up 100% by weight,
• for the production of a stain-resistant article, the staining tendency (ST) of the article being at most 15 and the staining tendency (ST) being reduced by at least 20% compared to an article based exclusively on semi-aromatic polyamides (A1).
