FIELD: writing and drawing accessories.
SUBSTANCE: invention relates to a simple or color pencil comprising three coextrusion layers: a non-foamed polymer based lead; non-foamed intermediate protective layer, surrounding lead and containing an ethylene (C1-C4-alkyl) acrylate copolymer individually or in form of a mixture with a styrene polymer; and artificial wood material based on foamed styrene polymer surrounding intermediate protective layer.
EFFECT: intermediate protective layer avoids problems with droppings falling and avoiding risk of loss of cohesion between lead and protective layer during sharpening operation; in addition, good adhesion is achieved regardless of the type of the lead polymer (polyolefin or styrene polymer).
