Definitions

  • the present invention relates to the field of artistic oil paints and oil bases for artistic oil paints. More specifically, the present invention relates to a method for the manufacture of an oil base for artistic oil paints, such an oil base per se as well as uses thereof.
  • oils used for the paint must have sufficient amount of triglycerides having a sufficient number of double bonds.
  • the drying of an oil paint involves formation of cross linking of the carbon chains of the triglycerides of the oil used by oxidation of the double bonds of the oil's fatty acids. For this reason, in order to ensure that the oil paint is capable of drying and capable of drying within a not too long period of time, the carbon chains of the triglycerides of the oil used must comprise a sufficient number of double bonds enabling such cross linking.
  • the drying process involving the cross linking is effected by oxidation of the double bonds by the air's oxygen.
  • the oil used for oil paints is linseed oil which has been heated to about 300 °C for a few days in the complete absence of air.
  • the resulting oil is called stand oil.
  • the stand oil has a sufficient amount of double bonds in the carbon chains of its fatty acid esters that allows the oil and hence also the corresponding paint made therewith to dry and harden upon exposure to air
  • oil paints have a propensity to blend into surrounding paint allowing very subtle blending of colours and thereby producing vivid colours with a natural sheen and distinct contrast makes oil paint based on stand oil the preferred technique to use by many artists.
  • oil paints indeed is capable of drying by exposure to air, the drying process is rather slow and when the drying is effected solely by exposure of the paint to the air's oxygen, the paint may take weeks to dry. For this reason, artists using oil paints based on stand oil usually add one or more drying agents to the paints when mixing the colours on the palette. The drying agent(s) added will considerably speed up the drying process.
  • drying agents traditionally added to the paints prior to application to the canvas are derived from cobalt, manganese, lead, zirconium, zinc, calcium and iron in the form of coordination complexes. These complexes are typically suspended in a volatile organic medium, such as turpentine or xylol.
  • drying agents examples include siccative and liquin. It is clear that the necessity of adding volatile organic solvents to the drying agents poses a health risk for the painting artist. This heath risk is related to the exposure of vapours of the organic solvents which may very well enter the human respiratory system and hence damage the human body.
  • Acrylic paints are based on coloured pigments or dyes suspended in an acrylic polymer suspension, optionally also comprising water. Unlike oil paints, acrylic paints are fast drying and does not necessitate the use of drying agents comprising organic solvents.
  • an oil base which according to a first aspect of the present invention is manufactured by a process comprising the steps: i) providing an amount of stand oil; ii) providing an amount of naturally occurring resins, said resins comprise at least 10 wt% of sandarac resin, mastic resin or a mixture thereof, based on the total amount of naturally occurring resins; iii) providing an amount of naturally occurring waxes, said naturally occurring waxes comprise at least 10 wt% of beeswax based on the total amount of naturally occurring waxes; iv) mixing said amount of stand oil provided in step i) with said amount of naturally occurring resins provided in step ii) and said amount of naturally occurring waxes provided in step iii); v) carefully stirring the mixture obtained in step iv) at a temperature which enables obtaining a homogeneous mixture; vi) optionally cooling the homogeneous mixture obtained in the previous step to
  • the present invention relates to the use of an oil base according to the second aspect of the present invention for artistic oil painting.
  • the present invention relates to a canvas for artistic oil painting wherein said canvas comprises an application of the oil base according to the second aspect of the present invention.
  • the present invention relates to a paint for artistic oil painting comprising an oil base according the second aspect of the present invention and one or more colouring agents.
  • the oil base of the second aspect of the present invention is in itself a whitish, partly transparent cream-like composition.
  • the oil base of the second aspect of the present invention is 100% non-toxic and its production and uses is environmentally friendly and can be used with any given additive such as a colouring agent as disclosed in a later paragraph.
  • the oil base of the second aspect of the present invention has great advantages in uses in artistic oil painting because the health risks traditionally associated with the necessary use of drying agents can be completely eliminated as disclosed in later paragraphs.
  • the oil base itself according to the second aspect of the present invention is environmentally friendly and comprises no poisonous ingredients.
  • the oil base virtually has no smell and it is completely miscible with additives traditionally and/or conventionally used in artistic painting, such as matting or glossing additives or the like.
  • the oil base of the second aspect of the present invention is a partly transparent paste-like cream.
  • the oil base can be manufactured in a way that makes it very viscous and dense. This has the advantage that in case the oil base is used for an oil paint, an artist upon use of the oil paint for an artistic painting can use that oil paint as is and smear it onto the canvas if he wished thick layers of paint. Alternatively, he can choose to blend in an amount of oil, such as bleached linseed oil, or even water in case the artist wishes to perform thin silk-like layers onto the canvas.
  • the oil base and the oil paints manufactured thereof additionally accordingly exhibits a modelling effect that allows an artist to shape the oil base or the paint applied to the canvas in a desired shape and the oil base or the oil paint will retain its shape and dry while maintaining the shape. These properties are highly desirable because if gives the artist great flexibility in adjusting the visual depth of each stroke performed with the brush. The drying itself will occur without any running of the oil base or paint and without any oozing of oily constituents from the oil base or from the paint.
  • oil base and the oil paints made therefrom do not make colours flow or drip when blending with similar paints of different colours.
  • All in all the oil base according to the second aspect of the present invention and the oil paints made therefrom according to a fifth aspect represents a high degree of flexibility for an artist making an oil painting without the known hazards relating to volatile organic solvents involved in traditional and conventional oil painting.

Abstract

Cette invention concerne un procédé de fabrication d'une base huileuse pour peintures à l'huile artistiques, ledit procédé impliquant les étapes suivantes : i) utiliser une certaine quantité de standolie ; ii) utiliser une certaine quantité de résines naturelles, lesdites résines comprenant au moins 10 % en poids de résine sandarac, de résine mastic ou d'un mélange de celles-ci, sur la base de la quantité totale des résines naturelles ; iii) utiliser une certaine quantité de cires naturelles, lesdites cires naturelles comprenant au moins 10 % en poids de cire d'abeilles, sur la base de la quantité totale des cires naturelles ; iv) mélanger ladite quantité de standolie préparée à l'étape i) avec ladite quantité de résines naturelles préparées à l'étape ii) et ladite quantité de cires naturelles préparées à l'étape iii) ; v) agiter avec précautions le mélange obtenu à l'étape iv) à une température qui permet d'obtenir un mélange homogène ; vi) refroidir éventuellement le mélange homogène obtenu à l'étape précédente jusqu'à la température ambiante ; vii) soumettre le mélange obtenu à l'étape précédente à un procédé d'étirage par soufflage par injection de vapeur dans ledit mélange pendant un laps de temps suffisant pour conférer un aspect brumeux audit mélange ; ledit procédé d'étirage par soufflage étant de préférence mis en œuvre sous agitation. Cette invention concerne en outre une base huileuse en soi ainsi que ses utilisations.
