In the early 80s, several new synthetic materials have come to be used in the treatment of canvaspaintings, among them Plextol D 360, Plexisol P 550 and Beva 371. Today, many conservatorsfind the information about the long term sustainability of these binding mediums to beincomplete. Evaluation of synthetic materials is mostly done through clinical research, sometimesartificial aging is simulated. The correlation between artificial and natural aging is however notestablished, useful information can therefore be gained through evaluations of actualconservation treatments. The intention of this study is to find out more about how thementioned products perform over time in normal museum conditions.

Works on transparent paper, also commonly known as tracing paper, have been described as ephemeral or temporary working documents and they usually number large quantities in archival and museum collections. They have therefore previously been considered of lower priority and can be found in poor condition due to a lack of treatment or suitable storage prospects. In addition, transparent paper can be very sensitive to moisture and reacts by deformation or loss of transparency. Due to the volume of these works and the necessity of treatment, there is a call for simple and efficient conservation methods. A common solution in archives for the treatment of water-sensitive works on paper has been the use of heat-activated tissues as they can be applied without the introduction of solvents. There is little published about the use of heat-activated tissues on transparent paper and is mentioned only briefly in existing literature.

Riksintresset för kulturmiljövården syftar till att så långt som möjligt skydda mot påverkan av kulturhistoriskt värdefulla miljöer. Miljöbalken, som utgör grunden för riksintresse för kulturmiljövården, hävdar att grönstrukturen inom och i närheten av tätorter särskilt bör tas i beaktning. Stockholms be-byggda ytor ökar, delvis på bekostnad av stadens grönstruktur. Utförliga strategier i Stockholm stads översiktliga planering för de riksintressanta kulturmiljöerna är något som saknas, framförallt för grönstruktur inom des-sa områden. Samtidigt existerar grönstruktur i olika form som element i alla Stockholms riksintressen för kulturmiljövården.
