The aromatic quinone is part of a six membered conjugated ring. The aromatic quinone comprises two oxygen atoms that are 1,4 (e.g., as found in 1,4-naphthoquinone). In contrast to benzoquinone per se, it is preferred that the aromatic quinone moiety is further part of an extended conjugated pi . system, such as found in naphthoquinones, and anthraquinones etc. It is preferred that the aromatic quinone comprises the core structure of napthoquinone, this encompasses anthraquinone.

The aromatic quinones may be optionally substituted provided that the substituent does not result in rapid intramolecular quenching of the excited state of the aromatic quinone. The rate of intramolecular quenching is dependent on two factors the type of substituent and the position of the substituent with respect to the carbonyl groups of the quinone. With reference to the structures illustrated below, structure (a) is not suitable because of the propensity for intramolecular quenching; it is seen that the amine is three atoms remote from a carbonyl of the quinone. The quinone of structure (b) is suitable for use with the present invention because the carbonyl is four atoms remote from a carbonyl of the quinone. 0 0
NH, 0) Oo (a) (b)
As one skilled in the art will appreciate not only an amine substituent would serve to quench the excited state of the
’ quinone; examples of other such substituents to be avoided . which are three atoms remote from a carbonyl of the quinone are: -OH, NR2, -NHR, wherein R is alkyl or aromatic. With regard to this intermolecular quenching, it is most ) preferred that the aromatic quinone used in the present invention has a half-life (t%) of greater than 100 ns in oxygen free benzene after irradiation. The half-life (t%) is the intrinsic quality of the aromatic quinone per se.
Reference to half-life (t}) as described herein is as described above unless explicitly defined otherwise.
The following are suitable aromatic quinones that may used in the present invention: 1,4-naphthoquinone, 9,10- anthraquinone, 2-methyl-1,4-napthoquinone (vitamin K3) which is widely used in chicken feed [the holistic approach to chicken nutrition and stain removal]. The preferred aromatic quinones are those based upon vitamin K3 or metabolites thereof. Vitamin K3 is particularly preferred because we have surprisingly found that vitamin K3 is classified as not photo-toxic according to the protocol as found in Annex II “B.41. Photo-toxicity-In Vitro 3T3 NRU
Photo-toxicity Test” of the Commission Directive 2000/33/EC of 25 April 2000 as published in Official Journal of the
European Communities EN. L 136/98 8.6.2000. 25. . The photo-bleach suitably undergoes one of the reactions set out above when excited by radiation falling generally in the - range 290-800 nm. For example, natural sunlight, which comprises light in this region, will be suitable for causing the photo-bleach to undergo one of the reactions described above. Preferably, the photo-bleach has a maximum
- 6 ~- extinction coefficient in the ultraviolet range (290-400 nm) . which is greater than 100 mol !lem™. Suitably, the photo- bleach is a solid or a liquid at room temperature.
Preferably, the photo-bleach is substantially colourless and gives non-coloured photoproducts upon irradiation.
The present inventors have found that photo-bleaches having a specified hydrophobicity, measured by their log P value, have a particularly preferred effect. All materials for the removal of stains also have a tendency to attack dye. The preferred photo-bleach systems have a particularly beneficial balance of stain removal versus dye attack tendency.
Preferably, the photo-bleach has a high log P value, where log P is the octanol-water partition coefficient. It is preferred that the photo-bleach has a log P measured at 25°C in excess of 2.5 and more preferably in excess of 4.0.
The Log P value may be changed by varying pendant groups of the aromatic quinone.

There is consumer concern with regard to chemical contact between consumer and the majority of chemical compounds.
Irrespective of whether the concern is judged to be warranted or not, the perception by the consumer is of paramount concern to producers of products. It would be desirable to be able to allay consumer concern by providing ] products having more “consumer friendly” acceptable photo- initiators. In this regard, vitamin K3 may be used also as a photo-initiator for polymerisation of monomers for the production articles, in particular food packaging.
The photo-polymerisation may be carried out with a chain carrier, for example an amine synergist, to improve the polymerisation process. Particularly preferred are acrylated amine oligomers as they will be polymerised into the polymer matrix and hence cannot escape.
The present invention will be further described by way of example only with reference to the following examples.
Example 1
The following three photo-bleaches were selected for comparison 2,4, 6-trimethyl benzophenone, Esacure KIP-150, and 2-ethyl-anthraquinone. Esacure KIP-150 is alpha-hydroxy- ketone based bond cleavage initiator and is available from
Lamberti Spa (Via Marsala, 38 21013 Gallarate VA Italy).
The benzophenone is an example of a non-catalytic hydrogen abstractor photo-bleach in contrast to the aromatic quinones of the present invention.
OE EE. Lo Ce . Palm oil stained cloths (Brazilian) were prepared as follows. Palm oil 0.06g was added deposited onto individual - woven white cotton cloth samples weighing 1.2g each. The cloth samples were allowed to age for 1 hour before being washed. Each wash consisted of four stained cloths, 200ml of 40 °C water and lg of Persil Colour washing powder (purchased in UK, zeolite based). The wash liquor was agitated for 20 minutes then the clothes rinsed in cold water, wrung and irradiated in a weatherometer for 18 minutes. The weatherometer is designed to simulate outside line drying and was set to give 42 W/m2 in the UVA&B.
The washes were duplicated but with the addition of 9 ppm of the photo-bleach to the wash solution, corresponding to 0.18% by weight on the powder formulation. : :
After the wash/irradiation procedure the staining of the clothes relative to clean white cloth was measured on a reflectometer and expressed as the deltaE value.
Esacure KIP150 = oligo [2-hydroxy-2-methyl-1-[4-(1- methylvinyl)phenyl]propanone.
The results are presented in Table 1. : Table 1 ' In the absence of photo-bleach a strong coloured stain is observed on the cloth, as indicated by the high deltaE value. The three photo-bleach result in bleaching of the stain and reduce the deltaE value. The results show that 2-
ethylanthraguinone provides a greater bleaching effect over the other photo-bleaches. It is evident from the results that the stain is essentially removed in the experiment where 2-ethylanthraquinone is employed as a photo-bleach.
Example 2
The following three photo-bleaches were selected for comparison Esacure KIP-150, Camphoroquinone (non-aromatic quinone), and 2-methyl-1,4-napthoquinone.
The same procedure as found Example 1 was used and the results presented in Table 2. meee
Table 2
The aromatic quinone provides greater photo-bleaching than the other photo bleaches. _ 20 Example 3
A 1.5 g sample of PEG-methacrylate was poured into a glass tube and sealed. A similar sample was prepared but with the . addition of 0.15% of vitamin K3. The samples were place outside on a sunny morning in February 2003 facing the sun at an angle of 10 degrees to the earth in Port Sunlight,
Wirral, UK. After 30 minutes the sample containing vitamin
K3 had polymerised, as evidenced by the formation of a thick } polymer film. A control mixture without vitamin K3 did not form a thick polymer film.
Photo-Toxicity Test ‘
Photo-bleaches were tested for photo-toxicity using the
Photo-toxicity-In Vitro 3T3 NRU Photo-toxicity Test” of the
Commission Directive 2000/33/EC of 25 April 2000 as published in Official Journal of the European Communities
EN. L 136/98 8.6.2000.
A positive result in the in vitro 3T3 NRU photo-toxicity test (PIF 2 5 or MPE 2 0,1) indicates that the test substance has photo-toxic potential.
A negative result from the in vitro 3T3 NRU photo-toxicity test (PIF < 5 or MPE < 0.1) indicates that the test substance was not photo-toxic to the cultured mammalian cells under the conditions used.
The photo-bleaches and the results are listed in Table 3 below, PIF values are quoted to 2 significant figures.
